Please place all orders through this web site. It will calculate the correct postage (which changes from time to time) and the MO sales tax for purchases to which it applies. And it gives me a record in my email archive of the order details.
PayPal is now the only way to make payment for orders. I don’t like their corporate anti-gun attitude, and you probably don’t either, but they’re the de facto way for (very) small sellers to take credit cards.
Please do NOT mail a check or money order, even if you remember the old PO Box address, as I no longer check that box on any regular basis.
