On May 3 I ordered a book for approximately $4.00 from Biblio.com and the order was cancelled. The author of the book had just passed away so I thought maybe someone else ordered it at the same time, so I ordered the same book from Ergodebook for $9.48 plus $3.99 shipping. I received an email that the book was shipped and the money was charged to my Visa No book arrived. I waited until the required 9-14 business days and called and was emailed that the book may not have been delivered due to postal error. In short, I was pretty much left with no choice but to get my money refunded after several requests to have the book sent to me after I noticed that Ergodebook now had the book I had ordered on the Biblio site at the cost of $46.78. This tells me that when a book suddenly becomes in high demand, Biblio and Ergodebooks disregards a customer who has in good faith ordered and paid for the book for the sake of receiving a better price. I can understand raising the price of a product in high demand but not at the sake of someone who has already ordered the book. Now I am left without the book and cannot pay the high prices being asked by booksellers. I think Biblio acted unethically and unfairly and I will not use them anymore. I warn other buyers to beware of having an order pulled out from under them should one of the sellers suddenly finds they are getting several orders for the item they (buyer) HAVE ORDERED AND PAID FOR.
