A supermarket opened up next to a small grocer and to show how much cheaper they were put a big sign out the front advertising butter.
The grocer used to sell butter for 50c a packet, but the supermarket advertised it for 49c. The next day the grocer put a big sign on the front saying:
Butter: 48c
The supermarket couldn’t afford to lose face so the next day it was loudly advertising:
BUTTER, ONLY 47c
However the grocer soon changed his sign to
Butter: 46c
This went on for days until the supermarket was advertising butter for ONLY 10c but the grocer still beat it:
Butter: 9c
The supermarket owner was now losing a lot of money by selling butter this cheap and went next door to the grocer to see if they could work out a deal. However the grocer wasn’t too concerned and didn’t want to. The supermarket owner said “I can’t understand how you can survive selling butter this cheap, I pay 40c each for it and so I’m losing 30c on every sale!”.
The grocer said “Oh, I’m only losing 1p on every sale, I just buy it from you”.
