At this time we accept payment by money order, check, or in cryptocurrency. We do accept cash as well, but there is some risk associated with sending cash through the mail. As explained elsewhere, we do not yet accept credit cards due the bizarre, heavy-handed policies of certain financial institutions.
Presently we accept Bitcoin, Bitcoincash, Litecoin, Dash, and Dogecoin. Prices are converted automatically by the software at the time of purchase, based on the current exchange rate.
