dear Tzippi,
The coupons I buy are not internet coupons, but rather coupons found and clipped from newspapers and magazines, and collected, then sold on ebay.
The Heinz Ketchup example was an expensive one, since those are popular coupons, but I generally get coupons for $.10 – $.20 each for Pasta, laundry detergent, eggs, etc.
I am fortunate enough to live near a supermarket that doubles coupons up to $0.99. I also have a large basement that is quite cold in the winter, so I can store a lot of this stuff.
That said, I still save thousands per year on groceries, with two teenaged boys with huge appetites.
Hey, how do you get the Sunday paper for less than $1/week?
