Jim, here is my experience and you can steal my words from my police lugers for sale...
Offer to do Money Orders and Paypal (I have always taken checks and never, ever had a bad experience).
For Paypal, request the people either pay the fee or send as a gift / thus no fee for you. Paypal is easy and makes it done and over with for you. Ask that folks send you their address in the REMARKS section, otherwise, you have to send them an email asking for it.
other hints
1. I keep a separate folder in my Outlook Mail where I drop all the sales emails pertaining to the item
2. I keep a folder at home with the checks/money envelopes, when I deposit in the bank, I write the amount on the envelope (i.e. if more than 1 item, 2 items, etc)
2. I keep an Excel document where I copy and paste each person's info, how many of the item they wanted etc - I only do this for more complicated sales, the books, raffle etc, you may not care
