I only ran into a problem 1 time, and in retrospect I am grateful for it! It got me 4 free boxes of cereal.
The buy 2 get 1 free coupon does not state anywhere on it that it cannot be used with other coupons. It does not say I have to buy the 2 items at full price, if that was the case then hypothetically you would have to wait until they weren't on sale, right?
As for the yogurt....200 in one trip is pretty extreme. That said....I have 7 people living in my house and if each one of them has 1 yogurt a day that would be 49 yogurts a week or 196 a month. Not that I would buy a months worth in one trip, lol. There are always deals for yogurt so no urgency there. I guess the bottom line is whether or not you need something depends on how large your family is and how often they consume that something.
