Untargeted Marketing

I was at the grocery store the other night, getting provisions for a poker game. At checkout, my cart contained a fairly manly list of items:

Refried beans
Velveeta
Ground beef (and not that "premium" 7% fat stuff, the nasty 20% fat kind)
Salsa
Tortilla chips
Nuts
Beer

After I paid, the checker handed me my receipt and a couple coupons - the kind that get printed out specifically based on your purchase.

The coupons were for - wait for it - tampons and diapers. Wha?
