NOTE: Sorry, no longer accepting Paypal for domestic transaction. Check or MO by mail.
May have exceptions for overseas transactions. My state, Virginia, and now the federal government have decided to require reporting of Paypal receipts to the IRS, resulting in the receipts being subject to federal and state tax. There used to be a $20,000 allowance to allow for hobby sellers to operate without taxing up to that amount. Now all Paypal receipts are taxed as self employed income so I lose about 45% to taxes and can't afford that. I don't operate this site to make money, and most of what I sell is about a break even for what I have invested, but can't afford to lose money on it. Sorry for the inconvenience, but we have our greedy government to thank.
