Worked in a grocery store when I was in high school. It was owned by a crusty old fart that didn't take much crap. One day a lady came in and told Mr. S that A&P down the street had round steak for $0.99/lb and it was $1.29 in his store. He asked why she didn't buy it at A&P and she said they were out. Mr. S looked at her and said, "Hell, if I didn't have any I could sell it 99 cents too".
Same principle. You can sell it cheap if you ain't got it.
