Reformed couponer here.
I used to get high off the feeling of walking out of the store with loads of groceries for little money. I had a dream stockpile that took up several Rubbermaid shelving units in our basement. We had tons of food to eat all the time. Guess what? We ate tons of food, all the time because it was there and we got fat.
99% of the items that manufacturers put out coupons for are for processed foods filled with MSG, high fructose corn syrup, and hydrogenated oils. The health and beauty products are filled with parabens, phthalates, and sodium laureth/lauryl sulfates. Toxic junk that we don't need in or on us. When I watch Extreme Couponers, I cringe at the amount of unnecessary stuff they buy. No one needs 100 candy bars, 2 liters of Coke, or frozen meals.
Extreme couponing is an addiction. It takes over your life. I've BTDT and am so thankful that I was able to see the light. Life isn't about getting good deals. It's about living happily and healthfully.
