Back when the Monopoly stamps first appeared, I was working for the local grocery store. The 1st few times they came out, there was a gameboard with 2 free stamps in every Sunday Paper.
Now, our store was a rather small one, however for some odd reason, we stocked alot of major papers, in addition to our locals. Living where i live, the demand for 40 copies of the New York Times wasnt that great. So at the end of the day we threw out all the papers, and what was inside, why 40 free Monopoly game boards. They would have otherwise been chucked in the trash, so me and a few co-workers ate lunch at Mickey D's for a week or two courtesy of the stamps.
I can recall a Co-worker at the same grocery store, getting in hot water for ripping pepsi points off 24-packs back in the early-mid 90's.
