Alan bought a new monitor for his computer and haggled with the shopkeeper to reduce the price dramatically.
Alan was over the moon with his deal and was telling Barry about the good price he got it for.
"It was even a better deal than I thought" said Alan "When I plugged it in to my computer and switched it on, Windows XP was installed on the monitor too.and it never cost me an extra cent, how was that for a deal"?
