Thank you. I don't know how many times I've said that to you.

You're very welcome.

If I order with the credit card of Kredu at Amazon .de, and the order worth almost 1800 dollars is not accepted, is this due to other factors than the credit card?

It's not possible to speak In general terms.

A declined purchase could be due to a number of reasons - unauthorized transaction, account verification required, mismatch of the account holder's credentials and the list goes on.
