Yes, Asylum Anime sells anime DVD for the same 
cheap prices.  Unfortunately, theirs are most 
definitely gray-market CDs as well, mostly on the 
notorious SM label from Taiwan. 

Generally speaking, anytime you see an "imported" 
anime CD selling in the $8-15 price range, it's 
almost always an SM or EverAnime knock-off CD 
from Taiwan.  The only exceptions are the 
officially licenced US releases, usually on the 
Animetrax, Pioneer, and Rhino labels.

There are also a fair number of counterfeit CDs 
with seemingly correct serial numbers floating 
around.  These are quite difficult to spot as 
fakes until you open the case and examine the 
disc itself.  (Legit CDs usually have screened 
artwork on the disc, whereas the fakes have 
simple lettering and no art.) The bad thing about 
these is that that dealers will often knowingly 
sell them for same price as real Japanese CDs 
(~$30).
