1 bid, smells fishy
Especially when this is sitting out there, still higher than I thought:

I've bought several times from QC. (But you really need to assess the books well...sometimes their grades are spot on, sometimes dreadfully off).
Anyhow, they are tight with what they accept via offers. Don't expect much of a discount. Go to their website, then you can make an offer on their non-ebay price.
Anyhow, yes, that doesn't really address your post, other than that I really wouldn't expect QC to shill their own auction, which is really a BIN in this case. They just don't bother accepting much below their asking price.
