For a "weekly special", I assume tied in with the pre-order of FIFA 11 for DS, Shopto.net are offering FIFA 11 for;
£24.85 on PS3 and Xbox 360.
£20.84 on Wii.
£15.85 on PC, PSP and DS.
To my mind, this is a great deal for a great game. And for those who didn't pick it up on release, this is the cheapest it's going to be until the January sales.
