Sales Tax for online orders

I just got a reply from the vendor, says they don't set the sales tax, that it is set by the Audiogon system.

In 23 I ordered several cords from The Cable Company out of Pennsylvania and no sales tax was collected. also recall KEF Warehouse out of New Jersey didn’t charge sales tax. I’m aware more and more states are adopting online sales tax policies. Sure does make one wonder if the seller pocketing that sales tax if he isn’t required to collect it. Conspiracy theories have begun.

Audiogon charges a service fee to buyers! BTW, ebay also charges sales tax with all purchases!

I've made a number of small purchases (music) recently from mainly FL and did not get charged sales tax or service fee from the vendor or Audiogon.

If your state has an income tax, read the fine print as you may have to pay on out-of-state purchases. In my state, you owe sales tax on new cars even if you paid it in state-of-purchase. Death and taxes.
