Just a follow up on my experience with
MPB, after eventually finding their replies in my junk folder, I entered into a transaction on a Friday, they quoted me a price for my lens against one of theirs, to which I agreed. My lens was picked up by DPD on the Monday, and had I been available to receive their lens it would have been delivered on the Wednesday. There was a post on here which I now cannot find, asking if
MPB paid the price they quoted, in my case they did exactly that. Furthermore, the price they quoted was £1.00 more than the price of the lens I was buying from them and they said they would send me the £1.00!!, in the event I chose a more expensive copy of the same lens and paid the difference.
As a matter of interest, the price they paid me was £50.00 more than the closest offer I had from LCE, and £80.00 more than Grays of Westminster, so although obviously less than I would have got from a private sales, I had tried to sell my lens and had had no interest so the matter was meaningless.
I am very pleased with the service received form MPB, and if I could have fathomed out how to do it would have given positive comments on trustpilot.
