This is a pretty good site that deals with coupons for groceries:
http://www.grocerycouponguide.com/When it comes to saving money on groceries, there\'s a lot more that you can do than merely cut out coupons from your Sunday paper. With an estimated $360 billion worth of coupons floating around, there are plenty out there to help you reduce your monthly shopping bill if you follow a few basic strategies. That is what this site is dedicated to doing.
There are a lot of sites and ebooks that claim you can reduce your grocery bill by 90% or more. Although this can be possible, you would have to approach shopping as a full time job to achieve these results. Since that is not an option for most of us, we have put together a practical guide that can reduce your grocery bills by 30% - 50% with a minimum effort. It\'s a practical guide for the everyday person who wants to save, but not make couponing their life quest.
The sections are not exclusive to themselves. Take a look and use the sections that fit into your shopping habits. Most are pretty straight forward and should not be a problem to integrate into your shopping habits. The more that you can adopt, the more you can save.
