I joined SU on August 1st and hadn't heard or seen anything so I had to call them twice to see when my order ws shipped. Kind of disappointing when you're totally excited to get started but I am trying to put a postive spin on the whole thing and say that it was due to Convention and the sudden influx of Demo applications.
But, yes, do call SU on Monday and follow up with them to check on the status of your order!
Good luck!
