In Arizona for many years, Safeway Foods sold "Safeway bucks' exactly like that at Christmas for... $2 I think (half went to a local charity.)

I have some set aside for my grandchildren.

I sent Safeway bucks to a few chip collectors years ago.
I am sure they were happier than the chipper that got a slabbed scorpian from me.
(Gosh. WHO Was that????)
