I thought the same thing also but after thinking it over she must have used money making coupons to make the the mustard free or else she would have paid $15.60 alone for mustard.
I buy a lot of high processed food because I either get it free or more then likely I make a lots of money on it which I use the overage to buy things that I would actually feed my family. I then donate the items my family does not eat to the food bank because I know if my kids were hungry and I had no means to feed them I would not hesitate to give them the junk.
Last week, I was able to snag 3 pounds of organic steak from Albertson's for 27 cents for the whole thing. It was in the reduction bin and had been marked down plus each package had $3.00 off in store coupons plus I had 2- $2.00 off any meat that I got for buying my son summer sausage for boy scout trip that he needed. Plus I had gotten the summer sausage on sale also.
I wonder about the stock pile of these people. I am sure it is mostly for the show. Any good couponer knows the cycle of coupons and store items. For example I know I only need a years worth of toothpaste on hand because every January I will get free toothpaste again. So any overages for the year in toothpaste gets donated. So I do not have this massive stockpile at the most I have a years worth of items.
Oh and the time these people are spending. INSANE! I spend at the most an hour a week and that is with me multitasking. I do not believe in binders. I keep it simple. Because we homeschool we get 10 newspaper on Sunday plus we have a newspaper subscription for a total of 11 Sunday papers. I pull out the coupons on Sunday and bundle. I write on top the date it came out of the paper and the last expiration date of the coupon. So I will know on any given date if I can recycle that set of coupons because all that is left is expired ones. When the sales flyers come out I take a quick cruise of them but I mostly match what I have with the blogs out there. I belong to several. I never cut coupons either. I just rip the page(s) that I need from the store as we grab that item(s) my kids continue to rip the coupon down to size as we are shopping.
