It's the age-old adage that we've all heard - if it sounds too good to be true, it probably is.

STAAHHP SHARING THAT COUPON, FOLKS. You know it's bad when the actual store is telling people to knock it off.

The coupon, which appears to give customers $75 to spend at the store, is not real. It tends to come up about once year, specifically during the holidays.

You know it's bad when Costco is even addressing it.

C'mon now, you didn't REALLY think that was a legit coupon, did you? I mean, stores love their customers, but not THAT much.
