Many are now doing an "Auto-renewal" & if you don't call & cancel they bill you. I just got this from Prevention magazine. First I got an e-mail invoice. Then they sent me a postcard stating if I didn't call by a certain date & cancel my CC would be charged. I called & let them know I was not happy I was being billed for something I didn't order & also not happy I had to use MY TIME to deal with this. Do not ignore these notices. Read the fine print or you may get charged for something you didn't order & then have to go thru red tape to cancel & get your money back. This is a new ploy they're using & should be illegal!
