PayPal only
Bad news–I have had to close my merchant credit card processing account. I can still accept credit cards through PayPal. The issue with credit card processing outside of PayPal is the exhorbitant fees. For a small, seasonal, low volume business, the fees are prohibitive. Recently, I was hit with a large new annual fee and the bank is applying it RETROACTIVELY! How fair is that? So I closed the account but they are holding me responsible for it anyway. 
( So, unless I can find a processing company with reasonable terms, please come to the summer art fairs armed with cash or checkbook. I will accept your personal check with identification. Also, we can arrange payment using PayPal. Thanks for your patience and understanding.
