I recall Chrisr (may have been someone else) explained ( a long long time ago ) that the credit card companies/banks withhold payment to Stanley "in case the club goes bust" during the coming season and, presumably, they would have to compensate season ticket holders.
Given that the 'early bird' concessions are designed to bring in money when there is otherwise less opportunity for the club to generate income, it's understandable, if this is true, that the club don't use credit card payments.

But I'm not at all sure if that's how credit card companies/banks do operate, or whether it's just how they treat all or certain football clubs.
