Go here to get a GMID if no one on this forum has an extra one for this month:

They got me one 2 weeks ago. The pricing is fixed. No dealing or haggling required. It will turn out to be roughly 2% over Invoice. If you are buying an 06, you will also get 0% or $2500 off. You will also get $500 off for GM Supplier rebate. Print out this and bring to the dealer when you're ready to buy:

If you are getting an 07, you will only get $750 cashback and no $500 GM Supplier rebate.
