For some time I have been a fan of FreeShipping.org, which is a great site to search for free shipping coupon codes. They just launched a blog called Go Frugal that combines tips from a number of savvy-spending bloggers, including myself!
Posts will share tips on how to have fun on a budget, how to look sharp for less, and many online bargains and freebies.
The site also has a new service called My Favorite Coupons, which lets users create a personal page that has their favorite coupons. You can get daily or weekly email alerts, too.
