Samsung Galaxy S8 Plus pre-order deals: what price should you expect to pay?

The Samsung Galaxy S8 Plus is set to be announced alongside its smaller sibling later this month at Samsung's highly anticipated event on March 29. Retail insiders have hinted to us that you'll be able to pre-order the phone on the same day.

April 21 is the expected Samsung Galaxy S8 Plus release date, so we imagine you'll be wanting to know what sort of price you'll be looking at and what pre-order deals may be available?

Samsung Galaxy S8 deals: what price should you expect to pay?

Predicting the best Samsung Galaxy S8 Plus deals

Seeing as we're still waiting for the official details, the best way to predict what the S8 Plus deals might be like would be to take a look at the launch deals for last year's premium Samsung flagship, the S7 Edge. Here's what TechRadar assessed to be the best S7 Edge pre-order deals one year ago:

UK: Pre-register at Carphone Warehouse
UK: Pre-register at Mobiles.co.uk
US: See all Samsung Galaxy devices at Samsung.com

FREE Gear VR | O2 4G | £129.99 upfront | Unlimited calls and texts | 3GB data | £36pm
This was the best Samsung Galaxy S7 Edge pre-order deal and even with just 3GB of data, it weighed in with a total cost only just under a grand. We're hoping to see the new phone also come with some tempting bundles, possibly the latest version of the Gear VR headset too. We were surprised to see this deal was only £50 more expensive than the same deal on the smaller S7 - something to consider if you're trying to choose which S8 to buy. Total cost over 24 months is £993.99.

FREE Gear VR | EE 4G | £129.99 upfront | Unlimited calls and texts | 5GB data | £37.49pm
This was the best Samsung Galaxy S7 Edge deal on EE during the pre-order phase. If you needed extra data it's even better than the above deal, costing an extra £1.49 per month for 5GB data instead of 3GB. As above, it was also just £50 more upfront than the same S7 deal. Total cost over 24 months is £1029.75.

FREE Gear VR | Vodafone 4G | £149.99 upfront | Unlimited calls and texts | 11GB data | £36pm
Vodafone didn't have the best of reputations last year, but things have improved since then. For just £20 more than O2's 3GB you could get 11GB data if you didn't mind Vodafone. Vodafone could be a network to look out for as it'll want to undermine the other networks, possibly by offering more data for the same price. Total cost over 24 months is £1013.99.

Three 4G | £49 upfront | Unlimited calls | Unlimited texts | Unlimited data | £62pm
We'd urge you to seriously consider if you actually need unlimited data on your new phone. If you do, Three is usually the network to go for, but you're probably going to pay through the nose for it. Compared to some of the other deals we've mentioned above, last year you'd pay at least an extra £500 on the total cost of the contract. Total cost over 24 months is £1537.

So it's a safe bet that the new Samsung Galaxy S8 Plus won't be cheap at launch. We're hoping the price won't be even more expensive than the S7 Edge was at launch, but given the pound is weaker than the South Korean Won at the moment and we've already seen the likes of Sonos and Apple use Brexit as an excuse to increase prices, it might be time to brace for even more expensive deals.

TechRadar's predicted Samsung Galaxy S8 Plus pre-order deal:

£149.99 upfront | EE 4G | Unlimited calls and texts | 5GB data | £39.99 per month
There will be cheaper deals than EE, but we'll use the network as an example seeing as it's the most popular in the UK. We're putting the upfront cost at £50 more than our predicted deal for the regular S8 and the monthly fee will probably be north of the £35 mark for a medium sized 5GB of data. Seeing as Samsung will be looking after its margins, we'd be surprised to seeing the Gear VR headset being thrown in for free again.

Time to go SIM only?

SIM only deals are increasingly popular nowadays as people choose to keep their phone once a contract expires. You can also save a lot of money overall by buying a phone upfront, then pairing it with a cheap SIM only deal. You can choose 30-day or 12-month SIM only deals, so there's lots of room for flexibility, ideal if you're not 100% sure how much data you're going to need. These deals start at just £5 a month too.

The S7 Edge cost £640 / $769 at launch. But we wouldn't be surprised to see that price increase given Brexit and the weaker pound. Not to mention Samsung need to rake in the cash after the Note 7 disaster. Could we see the upfront cost of the handset without a contract rise to £700? Don't rule it out.

That said, we still think it will be cheaper over the course of two years (the same amount of time as most contracts) to dig out the perfect SIM only deal after buying the phone upfront, if you're willing to pay the hefty cost of the phone all at once first.

Feel free to bookmark this page, as we'll be updating it with the official prices once they're announced. We'll also provide a comparison chart showing the best Samsung Galaxy S8 Plus deals from all the big stores and networks.

Unique, all-steel gas blocks expand the versatility of your rifle by providing a variety of accessory rail and handguard mounting options. Especially helpful in customizing short-barrelled tactical rifles. Machined from bar stock for extra strength and rigidity, then mil-spec Parkerized for exceptional wear- and corrosion-resistance. Low Profile version is a low and narrow, one-piece block designed to fit inside most free-float handguards; allows use of rifle length forearms on carbine length barrels for a clean, streamlined look and added gripping surface. Secures to barrel with included setscrews. Low Profile 2 is shorter and lighter than the Low Profile, and allows rifle length forearms to fit carbine-length barrels. Low Profile Slotted has a slot cut into the bottom for easy mounting and dismounting; slide the block into position and tighten the two pinch screws to snug it securely to the barrel.

AR-15, Issue:11, Page:016 Big Book Catalog, Issue:69, Page:015 AR-15/M16 GAS BLOCKS SADLAK INDUSTRIES Minimal Profile to Fit Under Handguard Or With Integral Accessory RailAluminum or steel gas blocks give the choices you need to create a custom-built rifle with a mission-specific configuration. Mounts securely to barrel with included setscrews. Clamp-on models squeeze around the barrel as you tighten the side-mounted setscrews. Slip-on models are anchored by setscrews on the underside. Low Profile fits under a free-float handguard and lets you use a longer on carbine-length barrels for a clean, streamlined look with more gripping surface. Extended Nose is like Low-Profile, but with an extended sleeve that covers taper pin holes left by the issue A2-style sight tower. Varmint fits heavy .936" O.D. barrels. Bull Barrel includes a 3-slot, low or high Picatinny rail for mounting accessories.

AR-15, Issue:11, Page:016 Big Book Catalog, Issue:69, Page:015 AR-15/M16 GEN II ADJUSTABLE GAS BLOCK SYRAC ORDNANCE For Easy Adjustment Of Gas Flow In The Field Or At The Range Refinement of Syrac's original adjustable gas block enables the shooter to fine-tune gas flow and rifle performance in the field. Designed to fit under free-floating handguards, the block secures to the barrel with two setscrews. The Gen II model eliminates the Gen I's release button, so you simply turn the gas adjustment setscrew with the included Allen wrench to one of 18 pre-set click detent positions. Click detent automatically locks in your setting; also makes "dialing in" predetermined settings for different loads easy. Standard Low-Pro models have setscrews on the underside; requires dimpling of the barrel. Clamp-On model wraps around the barrel and is secured with two side-mounted hex head cap screws.

Won't Interfere With Extended-Length Tactical ForearmsMinimal-profile replacement for factory front sight/gas block won't interfere with extended-length tactical forearms, while ensuring proper function of gas system for reliable cycling. Protrudes only .420" above barrel, covers less than 1" of barrel length, and adds only 1.4 oz. of weight. Compatible with M4-style carbines and M16A2/A3/A4-style rifles with any length, .750" O.D. barrel. Two steel setscrews keep the block securely anchored to the barrel to prevent shifting even under the force of full-auto recoil. Black oxide finish matches most factory barrel finishes.

One-Piece Design & Tough Steel ConstructionOne-piece, low profile, steel gas block fits under most free-float handguards for a clean, uncluttered look. Models available to fit .625", .750" or . 936" O.D. barrels. Locks securely to barrel with three steel setscrews.

AR-15, Issue:11, Page:015 Big Book Catalog, Issue:69, Page:015 AR-15/M16 ADJUSTABLE GAS BLOCK SEEKINS PRECISION Lets You Adjust Gas Output For Reliable Extraction/Ejection Steel gas block lets you adjust the amount of gas flow, so you can tune gas output for reliable extraction and ejection with different ammo types. Brass friction screw holds adjustments without thread locker and won’t mar the adjustment screw. Fits under free-float handguards on .750" O.D. barrels. Dual bottom screws secure block to barrel.

AR-15/M16 DICTATOR ADJUSTABLE GAS BLOCKS PATRIOT ORDNANCE FACTORY This 9 position adjustable DI gas block provides the ultimate range of adjustability and versatility. The addition of a suppressor typically increases the level of back pressure within the rifle system. This increase will prematurely wear parts and increase the amount of gas/carbon introduced into the chamber. With the Dictator, you can now control that rate of fire, gas flow and ultimately the reliability of your system. The Dictator is a low profile gas block, fitting nicely under rail systems with a picatinny rail channel of ½” or greater. Adjusting the gas system is easy, the front of the gas block has a dial that accepts a flat screwdriver, 3/32” hex wrench and dictation tool included in the Dictator gas block kit. The Dictator features a straight gas tube, but why? The advantage of a straight gas tube is that it eliminates the heat buildup that exists at the bent portion of a standard gas tube. This feature is extremely important for select-fire and/or suppressed rifles which are subject to very high heat levels. By reducing the built up heat, you now have a more reliable, longer lasting gas system. Each Dictator gas block kit comes complete with the applicable length gas tube. The 2 lengths currently available are carbine and mid-length. This gas block is setup for barrels manufactured for a .750 gas block.

Reducing the resistance between these components directly results in an overall increase in the rifle's reliability while the rings utilize the cycling action itself to scrape the walls of the carrier, helping shed fowling with every shot. The JPEGR-308 utilizes a one-piece design similar to the Mcfarland rings. Unlike the Mcfarland rings, though, our precision-ground gas rings are engineered to precisely suit DPMS-patterned carrier group components such as our own JP EnhancedBolt™.

The addition of a suppressor typically increases the level of back pressure within the rifle system. This increase will prematurely wear parts and increase the amount of gas/carbon introduced into the chamber. With the Dictator, you can now control that rate of fire, gas flow and ultimately the reliability of your system. The Dictator is a low profile gas block, fitting nicely under rail systems with a picatinny rail channel of ½” or greater. Adjusting the gas system is easy, the front of the gas block has a dial that accepts a flat screwdriver, 3/32” hex wrench and dictation tool included in the Dictator gas block kit. The Dictator features a straight gas tube, but why? The advantage of a straight gas tube is that it eliminates the heat buildup that exists at the bent portion of a standard gas tube. This feature is extremely important for select-fire and/or suppressed rifles which are subject to very high heat levels. By reducing the built up heat, you now have a more reliable, longer lasting gas system. Each Dictator gas block kit comes complete with the applicable length gas tube. The 2 lengths currently available are carbine and mid-length. This gas block is setup for barrels manufactured for a .750 gas block.

AR-15, Issue:11, Page:016 Big Book Catalog, Issue:69, Page:015 AR-15 GAS PISTON CONVERSION KIT ADAMS ARMS Makes Rifle Run Cooler & Cleaner With Less Felt Recoil Kit has everything you need to replace the standard gas system in your AR-15 and convert it to a reliable, positive-cycling, gas piston system. Eliminates venting of hot gases and powder residue into the bolt carrier and receiver for reduced fouling and less wear on the action. Feeds more smoothly, maintenance is easier, and the gun runs cooler, too. Short-stroke piston shaft eliminates concussive gas expansion in the upper receiver for less violent cycling and reduced felt recoil. Easy to adjust for three levels of gas release: normal fire, firing with a suppressor attached, or a single round fired without cycling. Picatinny rail on the gas block provides mounting space for a variety of front sights. Installation requires removal of original gas block, but no permanent alterations to barrel or upper receiver. Remove the piston system at any time and reinstall the original parts. Replacement handguard provides extra internal clearance for piston rod and has internal shield to protect your hand from heat buildup during sustained fire. Separate models for three popular gas system lengths:Carbine, Mid-Length, and Rifle. Pistol kit comes with a Samson 4" Free Float rail.
