I ordered three books, online, at a discount price from Discount Books. My credit card was billed for ten dollars more than what I was quoted. When I called, they told me only the first book is discounted. However, that was not what the Internet form indicated. Also, my credit card was then charged $19.95 for a membership in its club. I did not sign anything or indicate I wanted to join. I had to talk to someone, for more than fifteen minutes, in Manila to explain why the charge should be removed. The whole thing with Discount Books is a rip-off. I recommened not using them to purchase books. (signed) The USAF Navigator (Retired) read full review »
