Coin Show Question On Prices

Hey there...new guy here. I have yet to set foot in a coin show or even shop. OK...so it is expected that you haggle at the shows. Is it expected that you haggle in their actual shop as well?

Stores require more overhead than shows. (Lights, rent, employees...etc)
Expect less haggling at a store as opposed to a show.
Also, consider that the more you frequent a shop or a specific dealer, the better prices and merchandise become.
You get the, Hey, Look what I got, I was saving this to show you.

Yeah...I guess haggling with someone in their own shop would seem like bad form.

What about taxes? I'm assuming that you would have to pay sales tax in a shop but would not have to pay them at a show. Is that correct?

Yes and no on that one. Again at a flea market around me no one pays any kind of taxes at all. In some states even flea market sellers are required to pay taxes. At coin shows some dealers keep track of all sales for income tax purposes. They have to report an income so they must keep track of purchases, sales, traveling expenses, on the road expenses, etc just like any buisness. However, some smaller types of dealers that do such sales as a sideline, do not report any such sales. Again, sort of like flea markets. People that sell at a garage/yard/estate sale usually never report sales since they are only supposed to be selling their own property and that was already taxed when they purchased that item.
A coin store or any hobby store that sells coins and/or coin items is a buisness and must keep track of purchases and sales and pay sales taxes as well as income taxes.
So as to your question it is usually depending on if your selling coins as a buisness or just for getting rid of your own items as to if it's a buisness. Of course there are many people that sell at flea markets professionally and that is their buisness and they pay no taxes.
