I hate that show. So many reasons! Like a PP said, behind the scenes, TLC was paying the stores to violate their own policies, which was totally unrepeatable for any other shopper.
A 20 minute episode of an extreme couponer hurling insults at the manager because they won't give her a dime in exchange for her 2653 coupons, 12 cases of toothpaste and not charge her sales tax? Nope, everyone wanted to see the couponer jumping up and down while she loads the toothpaste into her minivan and flipping through her massive stash of coupons!
In Canada, all the fine print in any of our grocery deals, coupons, etc. all prevent extreme couponing. You cannot find a deal better than what the big companies provide to us ; we are just not that large of an economy.
And I am very on the fence about the "donating it to a charity" component. I had a past experience where a woman got so hooked on the feeling of donating and "getting a deal" that she spent tens of thousands into debt and her husband decided to file for divorce. We had to find the receipts from her donations and provide them to the divorce lawyer as proof of her "unstable behaviour" - husband's goal was to prevent her from taking the automatic 50% of marital assets. I don't know how the court case played out, but I do remember having to become a security guard and dragging donations back outside and reminding her that we had repeatedly told her, "We are reserving our right to refuse your donation!" it's one thing to give to charity and another to drive your household into debt as a result of allowing your mental illness to go unchecked!
I haven't used coupons in so many years because I rarely am brand loyal to things like cleaning products. LOL Stores don't issue coupons for "cheese" or "milk", it's a BRAND that offers the coupons for their brand only.
