With these coupons you could pick up a80gb PS3 for $400, or a 40gb for $320. I'm pretty sure this deal will work
with any other product at K-Mart aswell. 

(I wouldn't be able to test it seeing as there aren't any k-marts within a good couple of hundred miles from me). 

nope, there is 2 coupons, 1 of them is expires on the 21st. I've used several of them already, some of the employees were hesitant to give me and my friend the discount. It worked for me every time, but last time my friend went to buy wii play and they didn't let him, they let me buy FF6 on GBA though. They certainly won't let you buy a TV or something.

if people haven't done this yet they should try, i got a red DS, a digital camera, final fantasy 6 gba, 2 nunchucks and a wii play for 20% off. They won't let you use the coupon more than once a visit though. Only a few days left.

oh yeah i should mention last time i went to k-mart there was a suspicious guy that literally had 50 gift cards and bought every PS3 in the store. I think there was about 8 of them, i barely saw it but i had a conversation with the guy and he thought it was suspicious and they would look into it.

He bought 8 of them? Wow ... what a way to waste some serious money ... and besides, those coupons are for Kmart/Sears card members - not the general public. I would rather just buy a used 60gb PS3 anyhow ...
