Sales: Anyone have any numbers for the Amazon App Store? I've had some apps in there now for several weeks and they are just barely moving around the charts. I'm only selling perhaps 1-2 sales a day. I'd love to know how many sales per day to expect when you get at the following ranks: 100, 50, 25, 10, 5 and up. Any takers or guessers? Advertising: Where do you advertise your apps that appear in the Amazon app store? I'm having a hard time finding places to advertise. ?
