Only question I have is when you have a combination purchase (you bought a couple of stamps with you're $1,000 money order) does the bank exactly know what you purchased, as to give credit for some, but not all of the transaction?</font>
It depends on how the merchant sends in the transaction. A store like Target, Wal-Mart etc. swipes your debit or credit card in the same register that tallies your order. The full description of your purchase can be captured by the card network and thus analyzed by your bank. other merchants, like my local PO, swipes your card in a different machine. So no detailed information is sent. All the network and thus my bank sees is I bought $x.xx of crap at XYZ Merchant.
So when the bank sees a $230.81 puchase at 7-11, did I have a jones for a major brain freeze and got 200 Slurpees? or did I buy 2 money orders? And, how many miles should I get?
