Shapeways released the new pricing, so I fixed up all my parts at the store.

The ones that suffered were a few coloured plastic items and the white globe shrouds, with the remaining dropping in purchase price with a noticeable difference to the stern coin plates, sat dishes and gear shift plates especially the metal ones which is excellent.
