Have Coupons...Will Find Them

Since I use the coupon insert method for storing most of my coupons, I need a method to match my coupons with my grocery list.  Plus, there are so many sources for printable coupons out there.  How do match my coupons so that I can get the best deal?

• Coupon Database - I host a coupon database on my site that includes the insert coupons, as well as many printable and store coupons available.  You can search by a brand, product, coupon source, etc.
• My Personal Couponizer - I always have loose coupons that I need to file...either I printed them from online (since online coupons tend to come and go), cut them out of an insert and ended up not using it, or I received a freebie in the mail with a free coupon.  So, I'll search my Couponizer to make sure I'm not missing a coupon there.

With all my sources, sometimes it's difficult to determine just from the listings whether a coupon is valid for the exact item that I plan on purchasing without looking at the actual coupon.  When I'm doing my coupon matchups, sometimes I'll pull out a coupon (if I've not already used it) just to make sure that the coupon requirements match the item on sale, because sometimes it's not clear just from the listing.

How do you match your coupons with your grocery list or store sales?  Do you have a favorite online source that I don't use?  Please share...I'd love to find the "perfect" source. For more frugal ideas, please visit Life as Mom for a linky with more Frugal Friday posts.
