My (big metropolitan) supermarket chain got rid of their loyalty card program.

One explanation I've heard, is that so many people are purchasing with credit/debit cards, that most purchasers are readily identified and purchase history tracking continues unaffected.

And if you purchase with a credit card, one way those businesses bolster their bottom lines is by selling your transaction history -- down to individual items purchased.

It's enough to make one want to go back to cash...
