You may be right, but I have seen companies do this in ads, usually with the line "and we'll pay your sales tax." Also, friends of mine own a restaurant and the sales tax is included in the price. I'm in Pennsylvania if it matters. Still, for the states, the bottom line is that they get their revenue.
You would think, but you know nothing is ever that easy. Orchard does it out here in CA on some weekends. But I've heard it's illegal to advertise paying customers taxes in CA. So I don't know.
