Unfortunately the esteemed client forgot the full extent of the charge. The 1.70 was the internal UK postage cost, whereas the DHL cost from South Africa to the UK was ZAR50.00, or, a further 2 pound 50. So the total cost to the seller was 4 pounds 20, while the customer was only charged 3 pound 50. Not to worry, just a pity about the "bad press". Unfortunately not quite true. Thanks for the support anyway.
