Honstly I don't understand it, I've been seeing the same seller listing MvR red triplane for sale on Ebay at £126 for over a year now, I don't believe they are seriously trying to sell it, but I don't know what they are trying to achieve, maybe drive prices up in general because people think the planes have a greater value than original selling prices. Who knows.
Ships don't seem to be too bad, but that might be because there are no new players so a limited pool of customers.

I've just placed an order with Rarewaves-united for 3 ships to be supplied from the US, average price £12.40 inc postage. They are UK based and say there won't be customs charges so hopefully it's not one of those things that, if it seems too good to be true, then it is to good to be true.
