Yes. I bought ARTPOP 4 times (2 of those were on accident though ) and C2C twice with one of them being a mistake. I've bought a lot of other albums twice just to get the physical copy.
I bought I Am... Sasha Fierce twice. I got it when it originally came out, and then the re-release of the deluxe. It was only $10, and I broke the case of the other one, so I decided "why not?".
I have the original version of The Fame and the version of The Fame Monster that includes The Fame and The Fame Monster; not sure if that counts.
I own the Japanese and US versions of a couple of Hilary's albums.
I own the deluxe editions of The 20/20 Experience 1 and 2, and The Complete Experience, which has the standard versions.
