Alibris.com — non-delivery / refund shorted!
Alibris has just given me the absolute worst customer service experience. First they failed to ever ship my order and second, the refund they promised was less than the amount paid. Emails are answered by what seems like people on Prozak - actually they are probably employed by a third party service in Asia. The language is too flowery to be North American and the manner in which detail is ignored seems un-American.
I recommend shopping with a company that actually can deliver on promises and one that cares about it's reputation. Avoid Alibris at all costs.
