The UI is very easy once you get used it! It's so simple that even my 8 year old can use this tool without any problems (he just needs some help sometimes). I think there should also an option like "send me emails when i reach X sales" or something similar because otherwise people will forget about their orders if they don't check them regularly -.- So far everything works great though!! There isn’t anything bad yet :) Just try out amzone first before using others services which might not work well together ;) If your looking into selling online then yes go ahead buy all those other products look good too :P But keep us informed what kind o service do yuou want?
