They kept charging my credit card $12.00 for a membership I never signed up for. Don't know exactly how they get your information, however, it has something to do with buying products online. When certain online companies use Shopper Discounts to process your credit card you sign up for a membership; then they charge your credit card $12.00 a month. There is no way to cancel unless you give them a membership number (which no one has because you never even knew you signed up for the con-corporation) or your credit card number; yea, like I am going to give them my credit card number again. IT IS A SCAM!!! Stay clear of Shopper Discounts. They got me for $48.00!!!
