I ordered a book through DisccountBookSale.com on February 25, 2009. The next day, I noticed a $1 charage on my credit card for SmartSavings.com. Io found out that DiscountBookSale automatically enrolls buyers in SmartSavings.com for $1 a month so I cancelled the membership. Just yesterday, a new charge ($29.95) showed up on my credit card for HotBookSale.com. Apparently, customers of DiscountBookSale.com are also enrolled in HotBookSale.com for $29.95/month. I was unaware of this and did not cancel in time and they refused to refund my "membership fee." DO NOT buy anything from any of these so called businesses. read full review »
