You are required to not be a current subscriber. I've called and been told that means "not within the last 60 days." It's also been my experience that the calculation is from the date your subscription was originally scheduled to expire, not from the date of any extension(s). So if (1) you cancel delivery when you are traveling for more than a couple of days, (2) you tell them to extend your subscription by that number of days and (3) you travel a lot, you may be able to renew while you are actually still receiving the paper.
