Tangentially, they do have status cards, I worked at a wal-mart up north for a summer after high school and I used to have to type the number on the card into the cash register to override the tax on the transaction of people with a status card. The same wal-mart that banned people with a status card from buying mouthwash because they labeled the natives drunks and didn't want to propagate the issue. Yah seriously, that happened.
