Mals is a respectable record label and they have licensed a lot of albums from various labels. They have also released a lot of albums on their own.
I am unsure about their rights to sell licensed albums outside the ex USSR states. I don't think USA constitutes being a part of these states so I think you have a strong case if you want to file a complaint.
On the subject of online auctions: I bought a Kaipa album (Angling Feelings) from an online shop in United Kingdom which turned out to be a licensed album for the ex USSR territory (and I am not able to resell it again). It was a full price album and I am not going to buy anything from this online seller again. The lessons is to be very careful online. Sad but true.
