My first year I did not take credit cards and I have to tell you, it didn't seem to be a problem for most people. I was just upfront and told them while I've been making soap for a long time I am new to the business side and only accept cash. Do to the smaller price point it didn't seem to create a problem. Since I've added more products to my line I did get a credit card reader the second year. I started with Intuit and switched to Phone Swipe because of lower per swipe fees (2.69%) and 24 hour customer service (real people). The card reader was free and there are no monthly fees or contracts. I have the option to email a receipt to the customer also. You will find doing a Google search there are more and more merchant services jumping on board with these type of credit card services as this is another revenue stream for them with not a whole lot of maintenance. Interestingly, even though I can now accept credit cards--and I do accept AMEX as personally it's my favorite card to use (sometimes cost more to accept that one)--and clearly display this in my booth, I still get more cash than credit cards. But, it's nice to have it for those folks who don't have the cash!
