Yes. Although it sounds like I bought it online, I actually negotiated on line and went to the dealer to pick it up in person.
I sent a number of emails to dealers in an area of the country I heard were selling via the internet at substantial savings. (Check Edmund's Town Hall Forums for the prices others are paying for the model you are considering.) I simply said I was ready to purchase and would buy immediately from the dealer offering the lowest price. By the end of the day, I had my deal and saved about $3000 off what I could have bought it for locally. I drove out of state to pick it up. Easiest car purchase I've ever done.
