Does it not go on your status john? As in if your gold, like van driver, you get first look in. Next is the silvers, like ken, then the bronze and then the likes of me with no status. Not sure if an ambassador gold would get to see the prebooks before a regular gold, though it wouldn't surprise me. What about an ambassador with a bronze rating, would he still see prebooks before a regular gold driver? I don't bother much with it myself, just if its really quite in town, I might scour the suburbs with the app on.
