Inflated agreement, failed to cancel on request
This site is a travesty of their name. The try to get you to agree to a certain number of books, then later inflate the obligation and try and make you buy more.
I certainly would not get involved with them at all. They tried to inflate my obligation then turned me over to a collection agency when I refused to let them change the agreement.
Moreover, unless the books you order are KNOWN TO YOU to be written by competent authors, don't order the "unknowns" because the title intrigues you.
I batted 0 for 3 because they "sounded" interesting. They were poorly written and not worth the money.
