Many of us order books like they are going out of style, or at least I do. With all of the internet scams and identity theft going on it's hard to find a place to trust.
I must say that I'm highly impressed with amazon and those who sell their books on the site. I've been ordering books from them since 2004 and have 30+ in my collection from their various vendors.
One of my books had a cracked CD which was replaced but that is the only issue I've ever had. My books always arrive promptly and in the condition stated (or better).
One time I thought I did not receive one of my books and it was very simple to report this. They sent an email back stating the book had been shipped and the seller also contacted me to resolve the issue. Well I found the book right in front of my face and we all had a few laughs and it was over.
If you are looking to purchase books I cannot recommend amazon.com highly enough. It is an excellent site with excellent service. Make sure you check the book seller's ratings before ordering as this will ensure a trouble-free order, but I've never had any major issues.
Two thumbs up.
