I also failed last night trying to pay two different credit card bills with OV. In San Diego.
Went to a CVS right before 7/11 and my OV failed in San Diego as well. I'll wait and hope it comes back, but there is always MO or Evolve to get rid of these.
7-11 ATMs now is coded as cash advance as if you're withdrawing cash from the ATM. Therefore, the prepaid gift card scenario is dead. That's similar to money orders purchased from USPS. Time to move on!
Was dead for prepaids months ago, haven't tried recently. Valid debit cards (ie ST) still worked, but not very scaleable as they flag your accounts after too much volume.
