For what it's worth, I just tried to put through two test sales for different sites using my main Santander account
1. Selected a site, the purchase was smooth, the affiliate commision flashed up within 5 minutes
Approx 1 hour 30 minutes later
2. Tried another site, using the same bank account, everything exactly the same until I clicked "Complete the Purchase" at which point I see
ERROR(S) Card declined by bank. Please try a different card
I'm sure this isn't CCBill's fault, this is over senstive fraud protection from the banks. We must be losing a lot of sales to this. Strange that the first time it worked with this card and the second time it didn't; they most likely have software that is calculating probabilities, so the first transaction looked OK on it's own, but when the second transaction was attempted it started to look suspicious
It's worth noting that around 6 months ago I had the same problem with this bank account when putting through a test sale for a non-CCBill site. I spoke to the bank and told them to make sure they allow me to make purchases over the net in the future, they said they would change my account for me, but looks like it hasn't made much difference
