Since August, I have been dealing with a headache of a return, for a transaction that occurred at Midwest Folk & Fiber. I had already paid the state of Illinois the sales tax that I collected for all of my transactions there. I contacted the Special Events division of their dept of revenue, and she made it sound like it would be simple to get my sales tax refunded for that transaction--just get a state business license and she could cut me a check. So I went ahead and refunded that to my customer.
Five months later, I am still dealing with the fallout from this. Right now, I'm still too enraged over the latest salvo from the state of Illinois, which I got today, to get into the details. However, I do know that effective immediately, I will no longer accept any returns on sales made at shows. I will accept exchanges for the duration of the show. (I am still determining how my return policy for online sales will be affected.) I think this change is fair, as buyers are able to touch and see my products in person at shows, so they know exactly what they're buying.
The other change I will be making is to never do business with the state of Illinois again.
