You can sign up by check, the instructions are here:

Minimum check signup is $30 for six months. If you don't have a checking account, you can go to a drug store or bank and get a money order.

Please don't send $5 checks. It takes too much time to process a check (endorse, record, deposit, repeat) to make that a workable way to handle subscriptions.

thanks!
