At this point, I think a call every other day is in order. Seems they indicated back on the 10th that the order was a go. Here we are the 27th with no movement. Emails are easy to ignore, the person calling you every other day isn't. Based on interest expressed on the board, we're far from a huge customer but it sounds like we'd be able to put together a pallet every other month or so.
I'd call today, ask WHO you need to talk to in order to push this process along and follow the rabbit trail. A piece of paper is even easier to ignore than an e-mail, and I'd imagine that's exactly what we are to the person in corporate responsible for the next step.
That said, I'm a pushy SOB...and there's a solid reason that I did not volunteer to head up a group buy. Such things are a pain in the ass for the organizer of same.
