As a knife buyer, credit cards are essential, particularly for international purchases. In the past I have had to go to my bank and ask them to get me a cheque drawn on a US bank so I could pay a maker. I won't bother again unless I really, really want a piece of work. Generally, if I can't pay by credit card I won't pay at all.
I have been able to phone some strange foreigner
, give my credit card number and get my knife a few days later by airmail.
Other people use PayPal which also seems to work well enough but of course that requires the customer to have a PayPal account too.
