I absolutely hate this type of marketing. Whatever happened to honesty?
My son runs two businesses and it's always been an absolute concrete pillar, that the price he quotes is the price you pay. No hidden extras. It includes the dreaded VAT, travel and whatever else may be thrown into the mix. Totally open and honest. If you don't like the price, you don't book. It's that simple. If you're happy with the price, then he's delighted to accept your business.
Why is that so hard for thousands of businesses in today's world?
