GMID vs GM Supplier Discount

[MCaussade]

thanks everyone for helping me out with the info... now i have to decide whether the difference in "invoice" price and/or GM Supplier price would warrant driving an extra 50 miles to a farther dealership to save $$$...

another question... using the GM Supplier Discount, can I "build" an H3, or does the discount only apply to cars already on the lot?? (I ask because if you go to the gm supplier website it allows you to build all if not most other GM cars and price out the discount but not the HUMMER brand).... anyone know if the gm supplier discount applies if I'm building an H3??!????
