WelI could be teasing and say that as they were Americans on the phone then maybe they got confused with out Postal code? LOL.

Seem like posts are still moving so they are working through in some weird order known only to themselves (Possibly the order that the carrier pidgeons arrive?).

I expect that the emails go when the packs are loaded onto thepallets and then they all go out to UPS. I suspect it might be depot order that they are dispatched in.
