Sales tax on purchases internet verses shop

Hi
Being a European we are not used to having the tax added at the end and not on the as seen price of an article. Coming to the states this year to buy an RV and looking at all the extras we will need on line at the moment!
On line shops (Amazon etc) do not seem to add sales tax. Does this mean that buying at Camping World / harborfreight etc the prices are different on line to going in the shop?
Thanks

Sales tax is not included in list prices because every State can be different and manufacturers cannot price items 50 different ways! It is added at the time of purchase.
That's why it's different from European countries.
As far as paying tax on on-line purchases, as has been explained, the tax varies depending on the destination State and whether the seller has a "Presence" in that State.
That being said, and I don't know about other States, but Michigan expects everyone to 'fess up to their on-line purchases and add the tax to their annual State Income Tax return.
Right!
