The problem with every site I've seen like this is that when I search my address (~10 mins outside of the city), I get excited about all of the results, but when I go to order I'm told that they don't deliver to my location.

GeekWire recently ran a profile with some more background:

I like the ability to quickly comparison shop. Will use this soon and report back.
