I always thought that you didn't have to pay tax if you ordered macs from the online apple store until i got ready to place my order today. Are their any retailers who don't charge tax, or am i just dreaming....
You'll pay your state tax on purchases from any seller who has a physical presence in your state. Some mail order sellers (reputedly Amazon) do not charge sales tax on shipments outside of the state(s) where they are located.
