yep! i used to have a subscription. i liked them a lot for business type books, they were good. i got a year subscription plus a discount on an ipod with it... make sure you take advantage of that if they still have it.
I see a yearly subscription fee, but it only gives a discount on credits, plus a free number of credits. I was hoping to find a way to pay a monthly or yearly fee to get unlimited books. Anyone heard of a deal like that through audible?
