Hooray! Unauthorized charges from this company I've never heard of. This is a warning for any idiot who looks at all those weight-loss spam ads and figures, "ah what the hell, why not try it?" This is the why not.
The initial pills or whatever you're getting your free trial on may not charge you, but they'll get you with "trial memberships" to random sites you've never heard of; then you'll have to fight tooth and nail in an attempt to retrieve your money.

I'm currently trying to get my bank to reverse the charge, but I'm not very hopeful. God forbid banks ever start to believe their customers over other businesses.
