The store is based in Ohio, and the website clearly lists terms and conditions, going on to cite sales tax being added to sales within Ohio, and then on to spec shipping in HI/AK etc. I live in CA, but when I went to checkout on my purchase it added CA sales tax. WTF? I called and talked with some CS reps, and the manager guy I wound up on the phone with was a total asshole about it, which doesn't make me like them any better after just trying to hustle me with back door/hidden fees; finalizing my resolve to make this a public affair since their store deserves a warning label.
