Multiples Magazine is a quarterly magazine with seasonal issues slated for:
March, June, September, and December.
Multiples magazine is aiming to become bi-monthly or monthly by its 2009 issue.

Since the publication is so new and the first issue isn't coming out until December 2007, Editor-in-Chief, Candice Cain, has authorized Multiples to be sold through the Multiplesmag.com website for $5 for the entire year.  You will be able to subscribe through other subscription services, but you will get the best rate by clicking "Subscription" link above. If you don't want to subscribe yet, you can always try the first issue for just $1.75.
