Usually, I write about words. Today, I’m writing about numbers. Pay attention now.

CarpetRight ads proudly proclaim ‘UP TO 50% OFF, THEN AN EXTRA 20%!’

To the untrained eye, this looks like a whopping 70% discount.

Look again.

£100 x 50% = £50 off

£50 x 20% = £10 off

i.e. 60% off the original price.

Is this a trick you can use?
