Went by this morning to check it out. There were only a few games on the list in stock but I overheard another guy talking to the employee about the sale and he said he didn't know about it and it wasn't at this store. I had the CS guy price check a game for me and it wasn't coming up with the sale price so looks like this is a YMMV deal.
corporate didn't tell the stores, apprently. The games guy had to use a scanner on all of the games just to see what was on sale. though Halo 2 (xbox) wasn't on sale like the list said... and none of the other good games were in stock
Just got back from best buy and they had NONE of these deals (actually they had ATV Offroad for the PSP... but it rang up as 29.99... they had it for 25 percent off of that.) I did pick up an open box Xport thing for the 360 for 22.99 and NHL 2K6 for like 3 bucks.
Best Buy felt bad about the slick deals fiasco so they just marked 25 percent off of random things. (Marvel Ultimate Alliance! Tony Hawk Project 8!)
