Oldie but goodie.

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 50p a packet, but the supermarket advertised it for 49p. The next day the grocer put a big sign on the front saying:

Butter: 48p

The supermarket couldn't afford to lose face so the next day it was loudly advertising:

BUTTER, ONLY 47p

However the grocer soon changed his sign to

Butter: 46p

This went on for days until the supermarket was advertising butter for ONLY 10p but the grocer still beat it:

Butter: 9p

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 40p each for it and so I'm losing 30p on every sale!".

The grocer said "Oh, I'm only losing 1p on every sale, I just buy it from you".

Today butter in Britain costs between GBD4.74 and GBD6.56 per pound.
