Just to be clear, if I transfer $ from card A to card B, leaving card A with 0 balance and no issues and then have a problem with card B, you believe I will need to show receipts for card A, even though it doesn't have an issue since I transferred $ form there to card A?
Not going to bother transferring then and just use up card A then. Don't need to have to be concerned with it as long as I have card B, which could be a while.
I realize these are worst case unlikely to happen scenarios, but I'd like to understand so I can make the best decisions.
Thanks again
