Do you ever "buy" something that is free with coupon or pennies on the dollar, and later it turns out everyone hates it? That happened to me with the free Dano-nino yogurt. It just didn't fly at our house. I didn't even try to put it into smoothies. As much as I hate waste, I'm just not going to make my family eat something (or use a health and beauty aid product) that they hate just becuase "I got it free with a coupon!"
Shopping with coupons allows me to get free things every week. We get to try a lot of new products that I would never buy without coupons. Many things we like. A few things go into the garbage. If these yogurts were not perishable, they would have gone to a food drive.
It is important as home keepers that we bless our families with our frugal shopping. My goal is not to make my family groan over the things I bring home from shopping, but that it will be a delight. Let your money saving ideas be a blessing and not a curse!
