"I'm currently looking at buying a conroe and noticed the freezer 7 cooler was £14.95+VAT on weds, today it's £19.95+VAT"
Got one on Sat [it was still £14.95 on Friday night] from the shop but the person buying it for me didn't check the price and they nailed me for 33% more just because "it's do-able". That's what Clinton said when asked why did he do "it" ["it" being having his part-urinary "device" cleansed by some young woman].
Believe-it-or-not, some sales operations mark-up their profits strictly on a percentage basis, [usually quite low and fair but not low enough to be a disappearing "2-year cheapo wonder"], regardless, and don't rely of "sales tactics" or fanboy forums to play the camouflage price-game. That is called having a good principle in the first place and not learning principles through being streetwise.
