Wal-mart offers petrol discount to avoid interchange
This picture was taken yesterday at a Wal-Mart outside Nashville, Tennessee. Customers are encouraged to use their Wal-Mart private label credit card or the Wal-Mart reloadable shopping card. Both cards of course cost Wal-Mart nothing in terms of interchange.
(For those of you that track my whereabouts through my blog, yes, this post gives me away. I was in Nashville this weekend.)
