This reminds me of a time when I was a kid (a long time ago) there was a little neighborhood grocery store that had display space in the front window. The owner used to display fruits and vegetables there.
Frequently, he'd have little old ladies come in and ask "How much are the bananas, Lou?" And he always replied "A nickel a pound. 4 pounds for a quarter". You'd be surprised how many little old ladies bought 4 pounds..
