This company design the services that misleading and confusing the customer to give their credit card information, so the company may keep charging their customers without doing any services. That is the way the company make money. I bought my textbook online and register the free shipping twice. I did get $20 rebate, but the company use my credit information and keep charging for six months. When I phone them *******047, they said they send me a term conditions, which means no matter what once they sent a email to you, you are agree with the term condition. The company's service didn't require a conformation email to sent back to them. This unfair "agreement " make them charge $12.97 per month possible. I am so surprised that why this company still alive on the market? This company like poison that makes the online shopping market so stinky and toxic. Let us do something to protect online shopping security and safety on the market. Let the stinky ones out of the market.
