When I first signed on with CreateSpace, their payment terms were a bit vague: they pay when royalties reach a minimum of $20.00; payment is by electronic funds transfer (EFT) if you have a U.S. bank account; if not, CreateSpace will pay by U.S. dollar cheque but they “may charge a per check fee and accrue and withhold payments until the total amount due meets a minimum dollar threshold.” What that cheque fee and minimum threshold might be was not stated anywhere.
This has now been clarified: the minimum payment for U.S. residents is $20.00 if by EFT or $28.00 if by cheque, but an $8.00 cheque fee applies. Authors outside the U.S. are paid by cheque when royalties meet or exceed $20.00; there is no cheque fee. Foreign authors with a U.S. bank account can also receive payment by EFT.
