One of my points is that the sales data sent doesn't have to identify the merchandise, and even if it does it can be obscured. When Rural King starts losing sales because credit card X won't approve transactions, you can bet they'll fix that in a flash. You'll be buying $479 worth of Purina.
That is only $100 more than a jug of Garlon. Throw in a jug of Roundup
Pro and you are over.
