Question to ask yourself...
Do I need to coupon vs want to coupon?
In my case, I need to coupon! I'm financially poor! Robbing Peter to pay Paul & 7 brothers every month. Struggling to stay a float and having food on the table. That's my situation! Your situation may be different but we all could stand to save some money.
I remember that my grandmother had the shelves stocked at all times. We never went hungry. She stocked up on staples and household supplies. But not in my house....I can remember running out of food and making due with rice & beans for a few days to another payday. Never at my grandparents house did that happen. She saved and shopped responsiblilty.
So my reason is need to save money. I know that there is expense with couponing but it's only a few dollars a week to save many dollars. There is the time factor...but it's worth it in the money savings.
