If you enter your state and zip, you can see what your total will be (including tax and shipping).
If you want to pay by mail, fill in boxes and right click to print. Send with check or M.O.
At this point my credit card processer is PayPal. If you have never used PayPal before, it is really very easy to do.
There are two choices.
1) You can just fill in the card information as requested each time you make a purchase.
2) You can set up a PayPal account. To set up an account with PayPal, all you have to do is fill out the account information. You can even list more than one credit card. Then you will need to remember your password. In the future you can then use your account to buy from anyone (not only me) who takes PayPal.
All of your card information is on PayPal's web site with both methods and is never seen by me.
Thanks for shopping with NFT.
