Re-code.com contained a database of bar codes with instructions on how to print them on stickers. It suggested visitors "chose their own prices" by, for instance, sticking a bar code for generic cereal on a name-brand box in the store.
The Web site's creators called it a work of satire intended to create a discussion on how prices are set by corporations. It went online March 20.
A letter from Wal-Mart's lawyers to one of the companies involved in hosting the site said re-code.com encouraged a modern version of the old scam of taking price tags from a cheap items and putting them on more expensive ones.
