I sell supplies, and I wanted to ask about something I've noticed recently. This has happened twice in the last couple weeks: I've gotten an email from Etsy, saying "Etsy has issued a refund", and when I have clicked through to the order, I've seen that Etsy refunded the exact amount of sales tax that the buyer paid.

If Etsy is refunding sales tax, does that mean that these buyers have somehow registered as licensed resellers with Etsy, meaning that they don't have to pay sales tax on materials they buy?

And, if this is real, how do I sign up for it??? Despite selling jewelry supplies, I also buy a great deal of jewelry supplies on Etsy, and would love to get in on this. :)
