Be very careful when bidding. You need to be aware that first of all, a 15% Buyers' Premium will be added to whatever you bid. Secondly, on top of this total, 20% VAT will be added. This adds 38% to the price you think you are bidding.
I have bid on some stuff and not continued, because other bids place clearly don't understand that they will see a rather steep 38% nett added to their price, plus the cost of collection (no postal service offered, must be done in person).
Richard is only 30 minutes from this store and can collect for anyone who requires it, by arrangement, if I decide to bid on anything at the last minute taking into account the above charges. But I suspect I will not bid on anything as there are too many stupid bidders around who will fail to see the terms.
