About a week ago, I opened my Yahoo e-mail and there was an ad for a free sample for a dental hygiene pen, only pay shipping of $3.87. Today I received an e-mail from my credit card company asking me to verify charges of $87.00!! When I called the company to cancel the order, which I haven't received yet, I was told the fine print explained that I had a week to cancel my subscription to their services. Since I hadn't called to cancel the charges were promptly added to my credit card account. I am supposed to receive an e-mail from the company with instructions for cancelling the order, but I am doubtful. This may have to go to the Dispute Department of the credit card company.
