It's being rumoured that Sainsbury's and Morrisons will sell Call of Duty: Black Ops for just £25 at launch.
That's according to MCV, which also reports that GAME will offer the title for £24.99 if bought with any other in-store chart game on Xbox 360 or PS3.
Trade in Halo: Reach, Dead Rising 2, F1 2010 or FIFA 11 and you'll get it for the same price too.
Meanwhile, Gamestation will give an extra £5 of store credit to punters who trade in two titles against a Black Ops purchase, and will also offer the game for £20 when bought with an Xbox 360 4GB console.
The deals are set to run until November 14, MCV says.
"We've got more games, and specifically more copies of Call of Duty: Black Ops, than anyone else and we're also offering the biggest range of deals offering fantastic value," said GAME and Gamestation trading director Adam Davis.
GAME is opening hundreds of stores at midnight on Monday to sell the title as early as possible.
