I know somebody else posted the PSone+screen combo for ten bucks but mine didn't have that, they had just the LCD screen for $13 bucks which really isn't a bad deal at all. I picked up four at mine, they are marked down from $75. YMMV
Yeah, these deals are YMMV... both the Kmarts around here still had the screens marked as $50 and the PS1/LCD combo as $150. Amazing how they're still in business here.
