Newark is bizarre about shipping from Farnell. Sometimes you can order things from UK stock no problems, but other times not so much. Recently I was looking at a part that was insufficient stock in the US, but plenty at Farnell, and I couldn't get them to just drop ship the balance. The guy I spoke to on the phone told me they simply had no mechanism for doing that, and they'd have to go through an internal backorder that would take a couple of weeks.
