Using USAA

I've been thinking about getting the 13' 640i GC. I have USAA so I will be using the USAA car buying service and taking advantage of the saving, but my question is will you get the holiday credit ($3500) on top of the USAA discount?

Also, does anyone know if there's a big difference between the standard sound system and the premium sound system? There's a 2013 GC with all the options I want (driver assist package, luxury seating package, cold weather, full LED lights, 19' wheels, BMW apps) except premium sound. I'm thinking about getting it because the driver assist package is hard to find in my area, but I'm concerned about the standard system being crappy.

Thanks for your help.
