Would you be more likely to buy new gear out of state if there was no sales tax

Sales tax is legalized robbery. It exists because it is an efficient collection engine.  It also slows down consumerism. 

Lobbyists for retail corporations have argued in Congress for imposing interstate sales taxes on internet purchases as a way to force internet shoppers back into stores--they claim this unfair advantage is reducing corporate profits--even though they have also lobbied for and have successfully rigged the tax code to pay almost nothing in federal taxes.  Don't feel as if you are cheating anyone--it is mainstreet America that continues to be oppressed and cheated.  You deserve a tax break, as well.
