Bootleg anime cds

CD bootlegs are slightly trickier to spot

The CD will be made by either SonMay or EverAnime; both of those companies are well-known CD bootleggers.

Even if you can't spot these logos on the CDs themselves, you can usually ask the seller and they'll tell you if they were produced by one of these companies.The prices at which the CD bootlegs usually sell is around $10 (sometimes more, sometimes less). For a legit Japanese CD, that might just barely cover the shipping charges. If someone can afford to charge that little for a Japanese CD and they aren't running at a loss, then something fishy is up. This is a good sign that what you're being sold is a bootleg.
