I had something similar today, actually.
Guy came up to my register at the pharmacy, with a cutout from one of our circulars. Buy a Gillette razor or 4 pack of blades at $9.99, get an $8 coupon. The cutout consisted of the ad itself (which apparently had been located at the bottom of the page), plus, for some reason, the entire bottom strip from the page it had been a part of, with all the disclaimers and random numbers.
... Except the 4 pack of blades were ringing up at $10.99, the ad was showing packaging last used a year ago, and I could not find the deal in the current circular *anywhere.*
SC: "But it doesn't have a date on it!"
Me: "Sir, I cannot honor a deal I can't verify. Is there a sign where you got this from?"
SC: "Why should there be, you'll take this right now!"
Me: "... Because all our *current* sales should have a tag in front of the item?"
I ended up getting a manager, who backed me completely in refusing to honor the "deal." The guy stomped out, less than happy to have had his little scam figured out.
