This deal pretty much sells itself. It's a £20 card, that you can use to buy cheap games and themes and DLC, for £15.95 from Zavvi. This actually saves you £2 on the nearest competitor (ShopTo) and if you end up buying two, the current £3 off any order over £30 deal on at Zavvi at the moment will ensure more virtual money for even less of the real stuff.
This one has been off and on for a little while and tends to be highly stock dependent so one thing is for certain: you'll need to get your skates on to snaffle up a card or two before they all vanish into thin air...or the pockets of other gamers. You won't be able to use this overseas, but if you're a UK resident, and you've suddenly got a hankering for the new Borderlands or Army of Two DLC, then I suggest you hit up Zavvi ASAP and start spending less for more.
