I have what is almost certainly a stupid question resulting from me overlooking something painfully obvious, but here it goes:
Let's say you use Bank X's CC to load up the WF PPC. Why would Bank X care one way or the other if you were doing this repeatedly? From Bank X's financial perspective, isn't it no different than any other transaction? If you use the Bank X CC to buy $100 worth of candy vs $100 worth of WF PPC, is there any difference to what Bank X receives?
