Not to worry, I popped in to a local Currys by complete chance yesterday. They had one left on display marked up at £299 so i asked the guy if they were cheaper than the marked price. He went away and came back and said it was now only £49!
So I am now the proud owner of an almost mint WG3 in walnut and my Panny looks very happy on top. best of all my friend wanted an Oppli bench like my old one so said he'd give me £50 for it! So in the end it cost me nothing to swap
