I thought the state where the items were "being shipped" is where the taxes were going. So, since I live in Tennessee, when I make purchases it is tennessee state tax that I'm paying, not california, even if it is Amazon, Smith Micro or whomever. So far, when I purchase from Renderosity, I pay 10% extra (they are here in Nashville) :( When I buy from Daz, I don't currently pay tax. Though, I'm technically supposed to.
