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


There is a retailer that advertises in the Absolute Sound that you can buy gear from him without paying sales tax. He is located in Delaware where they don't have sales tax. Being from California that would save me 9.5 percent off the top and that is without even negotiating. I don't know if he charges for shipping or not but it seems like it could be beneficial.

Sales tax by all possible definitions is BS tax.
There's an income tax can solve all the taxes.
If there's a possibility to void than use it.
Sales tax is legalized robbery. It exists because it is an efficient collection engine.  It also slows down consumerism. 

All of the Internet Sellers I buy from (including Amazon and Tire Rack) add California sales tax to my purchases. But I'm moving to Portland in a week-and-a-half, so that's the end of that---no sales tax in Oregon! The State makes up for it in higher property taxes. 
I think when a Internet seller has a physical presence in a state they must charge sales tax. I think the technical term is Nexus.
Am I hearing, rather reading you guys correctly. We buy stuff on Amazon etc...with no tax, but must keep track of all these purchases and somehow pay the tax to state we reside in. I must not be understanding this correctly as this sounds, well....a tad unthinkable. I am not aware of anyone actually doing this. Surely I have misunderstood some here.
