The Left 4 Dead 2 price might actually be a price drop, as the PC version just dropped to $29.99 on the US Gamestop site.

Edit - Looks like the 360 version dropped as well...
I believe tomorrow's deal is My Sims for the PC.
I did get to see a list for the rest of the week. Not much good on there (and no prices yet). Friday's deal, however, looks pretty darn good and I'll be at my EB right when they open. :)
EB Games Lethbridge - Mayor McGrath has tons of copies of MGS4: LE. I picked up 2 sealed ones, just in case anyone on CAG needed copies. They still have quite a few left, both sealed & open.
