They also have their own website. Them, FYE, PopMarket (a couple others) all ship out of the same place (Omicron Court in something, KY - I believe). So, they're either different heads of the same snake or a like-minded cabal. Second going on their eBay though. Often have good multi-purchase deals
They're legit! Echoing the eBay sentiment. Their pricing differs across each of their platforms, but the eBay store (get-importCDs) tends to have the best bundle/shipping savings.
