No checks or money orders please. For both our peace-of-mind, I really prefer and recommend PayPal (or credit/debit card, which will be processed by PayPal). If you have a confirmed address, even better.
If you really want to risk it, I can also accept Cash in U.S. currency. (If you still need more advice not to do this in general: eBay cancelled my auctions that offered this option.) Please contact me first, though.
At the moment, I am only shipping by U.S. mail to U.S.A. locations.
