PayPal just sent me a notice that they were closing my account, for policy regulations. I guess I did not read the fine print, but they do not allow transactions of evil, wicked guns, gun parts, military surplus parts or hi-cap magazines. Apparently they audit or scan transactions periodically, and they observed where a purchaser referred to some magazines as "USGI".
Are there any other online, electronic institutions that conduct transfers similar to PayPal? If not, I guess it's back to MO or cashier's check.
