From Best Buy:
"Best Buy is dedicated to always offering the best value to our customers. We will match the price, at the time of purchase, on a Low Price Guarantee product if you find the same item at a lower price at a Designated Major Online Retailer. We will also match prices post purchase if we lower our price within 15 days of your purchase. "
Designated major online retailers: Amazon.com, Apple.com, Bhphotovideo.com, Crutchfield.com, Dell.com, Frys.com, hhgregg.com, HP.com, HomeDepot.com, Lowes.com, Newegg.com, OfficeDepot.com, OfficeMax.com, Rakuten.com Shopping, Sears.com, Staples.com, Target.com, TigerDirect.com and Walmart.com
So if your local Best Buy store can price match Amazon, Newegg, TigerDirect, Rakuten (former Buy.com/ Japanese version of Amazon/ pronounced "Rackten"), why would anyone want to buy online?
If your Denon has a 3-yr warranty and anything happens within the period, all you have to do is take it to your local Best Buy for free service.
If you don't like your purchase, it is so much easier to return it to your local store.
