The Coupon Project has put together a great Excel savings tracker. I am going to use it this year to see exactly how much I am saving since I have started couponing and where I could still cut back. Click here to see her blog post about this.
I think this is going to be an AWESOME resource to have around! Especially when my couponing gets called into questions (time vs. profit, etc.). :) Thanks, The Coupon Project!!
