Just for giggles, I checked CA, TX, TN, LA, IL and FL just to try a few. Every single Supplier Discount was identical. So I then called my good friend, who's the GM of a large Chevy dealership where I bought my ZR2 and ordered my 2500 HD ZR2 and he said supplier is supplier is supplier. It doesn't appear to matter where you live just like MSRP is MSRP is MSRP and that doesn't change based on where you live. The Supplier on my $87K 2500HD is $81,135 and I am also getting 100% of the hold-back and marketing dollars as well.
