I just came across a new website tonight called "Frugal Little Thing", and she has blown even myself away in how much she saved and how much she bought, and for that matter WHAT she bought.
Read through everything including the comments and questions at the bottom of her blog. She has utilized overages in a MAJOR way that she was able to buy more than $660 worth of groceries for less than $4, yes, that was not a misprint- $4.
Hope you enjoy and are encouraged. It is amazing to me the different levels there are to couponing. And what the value of coupons really are, especially when effectively. Click here to go to Frugal Little Thing's site.
