The importance of being able to do math in your head. At one of the shops I patronize, they had single serving sized bags of vegetable snacks on sale for 25 cents per bag. I put 10 in my cart. When I went to pay for them, the shop's owner told me that she also has them available in cases of 24 for $8 if I was interested in stocking up. I declined. Cheers, PW.
