I bought two kid thermos on sale at the beginning of the month, thinking we could use them in lunches. My oldest dd has been getting up a little early, making oatmeal with a chopped up apple in it, and bringing for lunch at college, after having some for breakfast. I have used for beverages in another dd's lunch. I think they have already paid for themselves! I was worried we wouldn't use them, but it has turned out to be a very good purchase.
Have you bought anything recently that exceeded your expectations, either in preformance or saving money?
