that's the trick with almost all subscribed items - check the label for expiration date. They start sending renewal notices within a couple months of an order. I will cut out a label, highlight the expiration date and stick it on my bulletin board. Then I just throw out all notices. This also applies to clubs, organizations (PBS is the worst) as well as magazines. I once wrote a letter to my local PBS station to suggest that if they stopped sending renewal for 10 months that they might not have to run as many pledge drives! I know it didn't have any impact, but it made me feel better.
