I just found a new way to find coupons online. It is actually a browser toolbar that you download and install into your browser. Once I did it, I could search through four different collections of grocery coupons.
Using the Free Coupon link I can find Printable Grocery Coupons (this is the four collections), Store Coupons, Printable Coupons, Free Samples, and Catalogs.
Using the Online Shopping link I can find Coupon Stores, Categories, Services, Daily Deal, and WILD. There is also a community with a blog to share your shopping finds and utilize what others have found to assist you in saving money. While this is new to me, I have already benefited from using it on my weekend shopping trip to the grocery store. I am by no means a super coupon shopper yet, but, I did save over 50 dollars this weekend!
