Though I was not exactly in a mood to sell one of my most prized possessions (Web Analytics 2.0 by Avinash Kaushik), I was intrigued by the email and decided to explore further.The process looks pretty simple. You search the books using ISBN, title or author, print a shipping label, package and send it across and get an Amazon gift card in return.
But I also wanted to check if there are other players in the market that provide the same service and guess what - there are lots of them. So how do you make sure that Amazon is offering the best price. With a little research I found bigwords.com which compares the buyback prices for quite a few buyback merchants. It seems that Amazon offers a pretty decent price as compared to other players.
You can use this service if you want to earn some money while disposing off your old books or you can make use of a book swapping service to get a new book in return. Either ways it's a win-win :)
