don't tell me it's free then ask for a CC#
I would say that most of the time it's like this: Say the item or service is trying to get a client or just plain sales of some sort, what their really offering you is usually a deal of the item free for a month and then you become a full time thing for them selling you the upgrade or whatever... Free for a month and then you pay, any other reason for the card# is illegal....
It's a free trial period and then you pay if you don't cancel. And they know that people will forget to cancel. And they don't make it easy to cancel.
