I found this mystery charge for $12 in my checking account. The description of the charge was pretty vague so I couldn't place where it had originated. The description said:
"POS Withdrawal SHOPPER DI 101 Merritt 7 800-889-8776 CTUS"
I googled the phone number in the description. After reading several complaints about this company, and looking back at my charges over the last 6 months, I decided to call the company. The person I talked to told me that they had sent me a confirmation email to my yahoo email address. It undoubtedly went to my spam folder. After some persistent complaining I was able to get the "customer service representative" to agree to credit my account the charges for the last 6 months. She did send a confirmation email of the cancellation and reinbursement, which has a confirmation number for the transaction.
I believe that the source of the mystery charge was from a $10 off your next purchase coupon that popped up on buy.com. I thought the coupon was from buy.com, but it apparently is not. The coupon was not in a separate 'pop-up' window, but seemed embedded in the buy.com checkout page. They (WLI Shoppers Discounts and Rewards) were somehow able to get my credit card information from the buy.com checkout page, where I had filled it in to make my purchase. Pretty scary. It makes me think that buy.com, and other websites from the sounds of the posts I read, have an agreement with WLI Shoppers Discounts and Rewards, which is very uncool. I will think twice about using these online sites ever again.
