I bought some stuff from auctions houses that buy returned stuff but what you get is very random, either as new stuff or complete junk. Coupled with the fact that there is no return policy on these returned items, non transparent pricing (they sometimes charge VAT and various taxes) and shipping is overpriced it's best to stay away unless you can go in person and check the items before you bid.
In any case the return ratio is priced in and we're very likely paying higher prices for new items to account for these returns.
