Yep.  Most networks prefer customer routes (get $$$) over peer routes 
(no exchange of $$$) over transit routes (pay $$$).  Simple math, really.

Ask your provider what community(ies) you can apply to your routes to 
get peer-level local pref.  Oh, and hope they don't make you go below 
peer-level local pref just to not be above it.
