BBTS isn't getting these distributed to them from InArt. They legally can't.
They're pre-ordering their own from multiple different places and reselling them. I can't imagine they're gonna make much of a profit, if any on these but it certainly helps direct traffic to their website.
They do the same with SHF, Mafex and other imports that can't be sold here in the states but they usually add the resellers tax to those.
InArt is just another import figure they're selling. Nothing has changed. They did add the reseller tax to InArt Supes tho.
