I agree. I saw an unnecessarily complicated arrangement on a Sarah Wait show, along the lines of "Buy 3 for 2" but if you spend £100, take 20% off with this code. I did try to work out if there was actually an extra discount in it but I gave up. When some of the Black Friday prices came in, they looked to me as if they were dressed up a little, in a Jess Foley "Pound to a Penny" fashion. Something normally costing £49.99 might be offered at £46.89.
(I see my old friend the brooch is finally reduced but it's 50% of the previous web price and still £14 more expensive than it was in auction.)
