I buy InComm SecureSpends and Vanillas from time to time, and previously could reliably buy 3 card or less of $500 each and never have a swipe problem, but am now getting these locked after swiping even if 2 are purchased together. 1 is still ok. Has InComm tightened the noose yet again? It's such a pain to talk to their outsourced streetshitters on the phone
