Actually the immediate shipping sounds good... However, based on past experience with Nashbar, their "It is shipped" type message really means that it should hit the mail stream in about 3 days. Then add on the usual transit time from their warehouse location, and you can get an estimated arrival date.

I like Nashbar, but I would bet that if I were to go to the Post Office and drop an identical package when Nashbar claims they shipped something, the receiver would receive it 2-4 days before they would receive the Nashbar package.
