Yesterday, I tried to make a purchase of a pdf and according to your website, the transaction was declined. My card is one of those listed as accepted. So I check my account. There's more than sufficient funds in my account. I email their customer service. They have no record of declining any transactions. And indeed, on my account's log, there is indeed a transaction for it that they accepted. So I think it's probably understandable that I"m wondering what's going on.
