I looked at my bill from E* today and noticed that they charged me $13 plus change for "sales tax & fees" on the $149 purchase of my 6000 receiver. They've never charged me sales tax in the past for either receivers or remotes or service. CSR said that it's what they do for hardware. I don't believe they have a physical presence in NY (I'm assuming that DNSC doesn't count). Is this normal or not? Is this legal?
