Ok, I finally got credit for signing up with Rhapsody on this deal. That should be one more bump for someone on the list.
The two easiest I have found so far are the rhapsody and audible.com. Both were 99cents and very easy to cancel once the offer is complete. And both were completed well within time for the next monthly charge. So far the gambing one has been the worst for me. Since they are not in the US, my credit card companies both declined the charges, and I had to open an account with some foreign company directly attached to my bank account. Talk about being scary.
Anyway, hope the next offer that comes along has better offerings.
