It could have been from one of those "Free" trials for home repair club, shopping club, yada, yada, yada. You get alot of points, but if you don't cancel you get the charge from $79.95-$119.95.
I did a trial once and it was a total pain trying to cancel on the phone, as they have to try 4 or 5 times to keep you on the call. Go back and look on you card statement for a charge for $1 to the same outfit........

Just a thought
