Is there anything can be done, preposterous egag sales tax?

Nobody said a word about sidestepping taxes. I'm talking about RAPING people that is way too much in egag's computerized nonsense. And much of what I buy through egag is new, like outboard service parts, I don't mind paying IF it is actually going to my state
40% is what you got charged? Really? Yes, there is something wrong there. Probably 4% and someone added a zero.
