Our local HN had a sale on this evening.
I bought a picture frame, which was listed at $50, with a 25% discount.
I did a quick calc in my mind, and worked out that 25% of $50 is $12.50, so the sale price should be $37.50.
But, I was charged $40.00. I questioned this, and , she showed me her screen which showed their calculation - they are doing this calculation.....
$50 / 1.25 = $40.
I did not really want to argue, as it was only $2.50 and a long line was forming behind me so I just accepted the cashiers argument.
I however, think my calculation is correct, but Harvey normans have been applying this calculation to all of their discounts tonight.
Lucky it was not a big screen TV :)
