I never really thought too much about it but in talking to my friend, who knows about ecommerce (he works as a programmer for a fairly large webstore). I mentioned the crazy hidden costs in shipping and how I just realized that the shipping is included in the taxable total. So not only do you pay $8-12 in shipping for one figure but you're also paying another $.56-$.84 in taxes on that shipping.
He asked if they have a brick and mortar store in FL since that's the only reason they'd have been charging me tax all these years. As far as I know they don't have any brick and mortar stores… which means they shouldn't be charging anyone any tax. I think they even charge Canadians sales tax (not sure about that though).
It's entirely possible, and I wouldn't put it past them, that they're just pocketing that sales tax they're charging us since they have no obligation to give any of it to the government.
This is all just conjecture though. Maybe since they sell products in physical stores through another party (walmart/target/tru/etc) that constitutes the same thing as having their own store. I am by no means an expert on tax law. I just have never heard anyone even bring this up.
