I actually DO have a license, since I don't live within a city limits I only needed to spring $10 for one from the state. You just have to send in your monthly sales tax report every month (even if you sold nothing). It's a fairly minor inconvenience, and it took me only a few minutes to get the license. I'm not sure what all the intricacies are, but since, to date, nothing I've purchased for resale was sold to anyone in this state, I haven't had to cough up any sales tax. I told the truth when I got my little retail license, that I planned to sell things on eBay (and at local swap meets if I ever had the time, I haven't yet) and would need a license in order to purchase wholesale. I've never had issues with rex distribution not taking my orders, but it's been a few years since I placed one.
