That makes for a £37 trade-in offer on £39.97 current-gen games

First I just want to share you a coupon code IGXEMATT51961

Fast Link:  Fifa14 FFXIV, Maplestory, Wow, Diablo 3, Runescape SWTOR, Tera, DDO, EVE, Tibia, Aion, Aion – EU, RIFT, RIFT EU, DAOC, GW2

So far it's for EA games only. Amazon's trade-up offer means you can upgrade FIFA 14, Battlefield 4 or Need for Speed: Rivals on PlayStation 3 or Xbox 360 to the PlayStation 4 or Xbox One version for £10.

This is how it works: trade-in a selected PS3 or Xbox 360 game and you get a £15 gift certificate for the game, plus, you get an additional £22 promotional gift certificate towards a selection of PS4 or Xbox One games. Amazon notes the £15 trade-in value is dependent on a game's condition.

That makes for a £37 trade-in offer on £39.97 current-gen games. Amazon is selling the next-gen versions of FIFA 14 and Battlefield 4 for £47. For some reason Amazon doesn't have a price for the standard edition of the next-gen version of Need for Speed: Rivals, but I can't see why it would be any different.

Usefully, you don't have to have bought the current-gen version from Amazon to make use of the program. All you need to do is trade in with Amazon.co.uk and buy the next-gen version from Amazon.co.uk to apply.

And, you can trade-in any qualifying title and be eligible for the discount on any next-gen title listed within the promotion. So, it works across console families (ie, PS3, upgrade to Xbox One).
