I started using coupons on my groceries and have saved hundreds of dollars. My monthly grocery bill has gone from $1,000 to $700.

I have always been frugal and used to love watching "Extreme Couponing." I even tried extreme couponing for a few months, but it was too complicated and time-consuming to track down newspapers, then clip, store, and organize coupons. Math is also not my strong suit, so I'd often end up paying more than I budgeted for when I checked out. I decided extreme couponing wasn't worth it for me, as I couldn't replicate the savings I saw on TV.
