If you buy books online from sites which are not that popular, chances are you've bought a book from a phantom lister. Technically, they are middle-men who own websites that have scripts which scour the net for books listed on other sites. They set their own [slightly] higher price for the book and wait for the buyer to pay for it. Once that's done, they order the book from the site where it's being sold and have the sellers ship the books directly to you. You pay more for a book which you could have got for less had you bought directly on a reputable site. If you are a book-lover, avoid sites which you've probably never heard of. Go straight to eBay, Amazon or any other reputable book-selling site. Why pay more?
