Are you trying to order online or in person? For the Denon here is what you do- go to 6ave.com and get their phone number, and call- you have to call them for best price, they will not give it out online, even in live chat. Ask them what their price is for avsforum members. Last month it was $1099 with free shipping.
If you want locally, verify that price by calling, then go to your nearest Best Buy or dealer with the 3808, and ask them if they will price match an authorized dealer who is selling it for $1099 on phone-in orders (do not mention them as a website). YMMV, but it worked for me.
