Like if you have digital coupons on one card, and you have digital coupons on a different card, and you scan both cards for the same transaction. Will the coupons from both combine and be applied to that same transaction? Or is it only the first card that is scanned that gets the coupons?
I know you can scan two different plus cards in the same transaction. I've watched customers accidentally do it. I just don't know about the digital coupons.
