I live in Pennsylvania. A state with 6% sales tax. Up until a few years ago I was never charged sales tax on items I bought on Amazon or Ebay. Amazon started collecting sales tax a few years ago when ordering direct from them but there was no tax added if buying from a marketplace seller who was not located in PA. Just recently though I've been getting charged PA sales tax for marketplace purchases, including when buying from sellers who are not even in the USA. And I swear I see this now on ebay as well. Has this changed recently? Anyone else seeing this?
