I was thinking about the supermarket discount cards I have (one from Kroger, one from Giant Eagle, both in the Columbus, Ohio area). I thought: I have extras. What about putting one in a cache and having 'cachers use it on their next purchases? Yeah, it would screw up Kroger's attempt to get to know me, but who knows what weird offers I'd get in the mail. Anyway, has anyone else thought of this? Just curious what y'all think of the idea...
