One of the most popular magazines in the US is People magazine. If you are seriously considering a People magazine subscription you will find here some interesting reviews.

Based on the short review and my own experiences I can definitely recommend magazines.com as the site that truly stands out from other sites as regards magazine subscription, especially for residents of the U.S. They are experts on what they do and they are experts on magazine subscriptions. Although Amazon is an excellent site, their wide variety in items sold prevents them from providing this specialization and touch that would give you the feeling of completeness. As far as magazine city is concerned, they are great if you wish to order your subscription from around the world including United States and Canada. If you live in America however, your best choice would be magazines.com
