Here is my experience (and thanks to the other posts in this forum for helping me ask the right questions/make the right decisions). 
  
Yesterday I saw that my local dealer had a 2013 Edge in stock that met my preferences (Limited,AWD, 302A, Towing package) and so I stopped in on my way home from work to get a price.  I was pleasantly surprised to find that the dealer could offer me an X-plan price (a deal through my employer that I did not know about).  With the $500+$500 rebates (including the incentive for Ford credit) the price looked good, but not quite a slam dunk.  The seller asked me if I had received any customer cash offers in the mail.  I think I have had some offers in the past year, but I know they ended up in the recycling bin.  The seller told me that "they could look up online to see if I qualified".  I left the dealership and went home and took a closer look at the offer. It was pretty good and I knew I would be happy--if I could get the additional $750 discount. 
  
So I went back into the dealership today and told the seller that I wanted him to check online to see if I qualified for the $750 "private cash" *and* I told him that I would buy immediately if I did qualify.  He took my driver's license, went back into the back to check and came back in about 10 minutes with the good news--tonight I am a happy owner of a brand new Edge.  What a nice ride! 
  
The only hitch in the deal was there was a $399 charge added in for VIN Etching.  I asked the seller why and he said it was an option and I could tell the finance guy that I wanted it removed.  I did have to ask specifically to have this removed--the folks at the dealership seemed almost sheepish about the charge and I got no push back. 
  
Overall a good experience--I have been reading the Ford Edge forums for the last couple of months and everything I learned paid-off today. 
  
Thanks!
