One more piece of advice. Credit Cards. Someone had pointed out on a previous post earlier this year that once they started taking credit cards at craft fairs, the number of items purchased increased from 1-2 to 3-5. I took that to heart and signed up for "Square". I cancelled within days for 1 reason. No Phone Support. I needed to find out why it worked on my IPhone, but not my IPad. I chatted with a technician on line who pointed me to a URL that described how to "Swipe" a card across the reader. I dumped them once I found out there is no number to call. I went with Intuit, 24 hour phone support and same fees as square. So we have our next craft show this weekend so I will update you with "Things I should have thought about in Advance".
