Your card might be high risk. This issue is uncommon since we have relaxed our risk thresholds somewhat. However, if your card is deemed too high risk or we see any fishy activity, we might have to deny your payment. Our merchant has a limit of 3 attempts for each credit card. If your banks security measures interfered with the first few attempts, you may be capped on the number of transactions you can make for the day. Please ensure that your bank is squared away, then to be safe, wait 2 days to order again.
