I just made an eBay purchase and eBay added on sales tax so I guess depending on your state you may have to pay tax. I think they messed up I’m in NY an out of state vendor who does less than $300,000 in the last 4 quarters doesn’t have to register for sales tax but eBay decided to make it easy and they are charging anyway. I guess I will see if I can call companies direct to order. You have to check your state rules to see what’s going on
