Just had an interesting experience at a Target.
The store i went to matches RC to CC and DL. After checking all three, the guy handed me back my DL and swiped my RC to load $1,000. He then swiped my CC and i signed the monitor, but the card only took off $0.46 and i had to pay with a different card. I called my CC company to see what the issue was and was told no charges were made that day. I checked the receipt and saw that the guy swiped my RC two times and it withdrew the $0.46 that was left on the card.
So aside from the manager being a bit incompetent, how does it work loading a RC with the same RC. Not that it accomplishes anything, but does it count towards your monthly limit?
