I was a long time user of Bibliofind, and
recently I used it under its new amazon name. The three
transactions I conducted were very smooth, and actually easier
than any book buys I have done on the old
bibliofind.com or amazon.com's retail arm.
It does give
you a variety of books from different dealers at
different prices, if you go in by typing in bibliofind.com,
and letting it kick you over to amazon. If you go to
amazon.com, it is easy to wind up on their search listing
service which is a waste of time.
It seems this
service is changing under the guise of improving every
day so maybe it is getting worse or will get
better.
My two cents anyway.
