I second these statements. I don't really like Tandy products at all, but with a few exceptions. They've disappointed me too many times. Anyway, with a seller's permit you don't pay taxes upfront for your materials (with the understanding that you will collect taxes from your customers when selling your finished goods) and many suppliers offer wholesale or reduced pricing.
Registering for a seller's permit here in California took no longer than 10 minutes and I was able to print the official permit out at home in the same sitting. I brought this to Tandy and I now get pricing at or lower than Elite pricing, with no annual membership fee. If you don't have or want to bother getting a permit for yourself, you can use a business owning friend or family member's permit. Just present the document at the counter.
