Overheard II

Here's another snippet of conversation I overheard - this time at the grocery store.

Wife: Why are you getting two milks?

Husband: I got two half-gallons instead of our usual gallon because the half-gallons are two-for-$3.00, and the gallons are $3.89. We'll save 89 cents this way.

Wife: Yes, but we never go through two milks in one week!

(By the way, she wasn't blond!)
