I just purchased a new Edge Titanium. I have been a longtime customer of COSTCO, have never checked into their purchase program. I went online filled out the forum and sent it in. It returns a build out form, gives you sticker, and invoice prices. It also gives a couple dealers that are in the program and a couple people at each dealer that you should deal with. I got a call soon after. The salesman new what I wanted by the information I had sent in. Said Costco demands they show the invoice to you, They can only ad $100. to the invoice. Easiest deal I ever made. You can still try and get some of the hold back, but it sure starts you at a good point. I had a couple quotes from other dealers, this blew them out of the water. I have been buying a new car every couple years, this was the easiest ever.
