Not sure when choicesuk's 10% off voucher expires, but use the code tech0107 to get 10% off all your orders.
I'm uncertain as to whether they take the money off now or later (I presume they don't take it off until dispatch but perhaps someone could clarify this).
Anyway, here's some of the game that you will definitely not find cheaper anywhere else: -
Super Mario Galaxy - £27.89 (inc discount)(2nd march)
Metroid Prime 3 - £27.99 (inc discount)(2nd march)
Super Smash Bros - £27.99 (inc discount)(30th march)
Sonic: Secret Rings- £28.79 (inc discount)(30th march)
These are just some of the most eagerly anticipated titles, there are plenty more on there to preorder and buy using the discount code. Remember, all prices are inclusive of delivery!
