Places are required to charge sales tax if they have even one person working in the state where you live (one person alone creates a tax nexus). Here in Wisconsin, if you buy something online (EBay, Amazon included) where the seller doesn't charge tax, you are required to report it on the next years tax return and pay sales tax accordingly. Of course many don't, but to me it's not worth the potential for hundreds of dollars in fines for not reporting it.
