FC: Fed up with those supermarket discount cards? Make your own

[Declan McCullagh <declan () well com>]

Me, I hate those Giant discount cards that you have to give up your 
personal information to get. This is the free market at work, of course: I 
value my privacy and relatively-empty meatspace mailbox more than the 
discounts I'd receive. Besides, I usually shop at Fresh Fields on Wisconsin 
Avenue anyway. (For those of you outside the mid-Atlantic states, Giant is 
a large supermarket chain here.)

Swapping supermarket cards has long been a staple of cypherpunks meetings, 
of course, but Rob Carlson has taken it a step further, and I thank him for it:
