Best Buy, Target, WalMart, Gamestop, Vintage Stock, Costco, and many other retailers; at least one the store that sales electronics will have'em.
There are more than enough Online Stores that are selling $299 PS3s as we speak, you just have to search.
So what if they have to store browse? It's been done a millions times before, no big deal really.
I highly doubt PS3 $299 is in complete drought.
- 2010 MUST Haves: WKC, Heavy Rain, GoWIII, Fable III, Mass Effect 2, Bayonetta, Darksiders, FFXIII, Alan Wake, No More Heroes 2, Fragile Dreams: FRotM, Trinity: SoZ, BFBC2.
- Older Need To Buys: Super Mario Bros. Wii, Mario Kart Wii, Deadspace, Demon's Souls, Uncharted 2.
There is definitely more to list that I want, but that's my main focus there.
