I understand buying apollo escooters is a tax free purchase, why is that? What’s the story? Is buying from canada tax free?

Sounds like there is quite a bit to it, but if you don’t have a physical presence in a state e.g. business location then you don’t have to pay state sales taxes. I guess it’s also possible that taxes are being paid and already built into the prices.
