There are only 2-3 copies of normal version ARTPOP and no deluxe version of it where I live in every store. Some of them even has none. So I think that's true.
she's become undraggable hit album, hit singles, hit tour, hit household pet, hit octogenarian duet-maker, hit iconic moment 'yaaasss gaga yaaass', hit boyfriend
only the queen i feel sorry for the haters at this point
So if I pretended BTW sold 8M my comment about shipments not being sales would hold more weight to you?
If you stopped pretending BTW stopped selling before she began a massively successful tour you'd agree with most others it's likely in the 6.5-7M bracket with 8M being an inflated even for shipped most likely. But please, underestimate ARTPOP's sales to 1.7M because you know this to be accurate over any tracking available online.
You all act like using actual sales numbers is shady.

those numbers are DISMAL. she went from selling 14 million to 2 million in about 4 years
