What is extreme couponing?

Extreme coupling is about finding the items your family USES and creating a small stock pile at the lowest price possible. Here we have 30 bags of dog food, 16 tube of body lotion.. Retail value $146.20 before taxes.. Total OOP: 12.43!!!!! PLUS I got an additional $44.50 in coupons from Iams, making this a $32.07 money maker.. Can you say SWWEEEET!
