As Heminator said, "invoice" is not what the dealer pays. In fact, as buyers have become smarter and figured out numbers such as "invoice", dealer holdback, etc. "invoice" pricing has become this arbitrary number so dealers can still make some profit. That being said, the Dealer Discount is a discount that the dealer will put on a truck that is separate from manufacturer rebates/incentives. Dealer Discount will always vary from dealer to dealer. Here in California, I've seen dealer discounts range from $1,000 all the way to $6 or $7,000.
With the corporation discount you have, you're "locked-in" deal is 1% under "invoice." That "invoice" amount is what's listed on the truck's build sheet that your dealer can print out for you, then the dealer will subtract 1% of that amount. If the dealer won't show you this build sheet with the "invoice" pricing, you can build the exact truck you're looking at here (

Unfortunately, and this is just in my experience, if you play your corporation discount card right off the bat, the dealer won't budge from that discount. That's as good as you're going to get...that is, 1% under "invoice" plus all applicable manufacturer incentives/rebates. You most-likely won't get a dealer discount on top of that corporation discount, because in the dealer's eyes you're already getting a discount (that discount is the difference between MSRP and "invoice") so why should they offer an additional dealer discount. If you withhold that little bit of information at the beginning, you keep the upper hand in negotiating power, and might be able to negotiate a better price than you could have gotten with just the corporation discount. Not saying that will always happen, and if negotiations aren't happening, then you can either a) find a new dealer to work with or b) pull your corporation discount card and the dealer will have to honor that.
Sorry if I completely lost you haha
