Hi, i went to get my free trial (wich is not really free if you have to put your credit card to get it), but as soon as i got it i was charged 0,88 cents, now, i know this isn't much, but come on, if it's free its free, did anyone else got that?
Payment processors typically charge you a symbolic amount, like $1, whenever you register for a subscription service to verify that everything is in order. It only serves as a test though, and the fee will be refunded shortly after to your card/bank.
I remember PayPal doing this the first time just to check that the card information is correct. Might be the same, in which case it should not actually be charged, or refunded after checking.
edit: Ah, already beaten to it by an official response.
