Gamestop: $20 Off Any One Pre-Owned Video Game

Background:

I have a $20 Off Any One Pre-Owned Video Game reedeemable at Gamestop, it expires on 31 January 2013.

Question:

The coupon is printed with a barcode, and serial number (or coupon code?) below the barcode. It is from the Power Up Rewards. I found the coupon on the ground outside Gamestop. I don't know if it has been used, and that's the issue. Can the coupon be used again if it has already been scanned because it may contain that unique number below the barcode, or is that number just a coupon code, and I just lucked out by finding it ?

As always, your responses are appreciated!!!:lol:

No it can't be used again if it was used. The barcode is tied to the account it was assigned to. I'm not sure you can even redeem without the membership card it was assigned to.

Ok, thank you for the response, thats the reason I was asking!!!!! If you'd like delete your post, and then I'll delete both of mine and remove the thread.
