The app is easy to use. Been a seller for two years now, over 1200 sales. One thing I would change is being able to view older messages in one message thread. Another problem is the lack of photos you can add to a listing. There should be bare minimum, 6 of them. Customers want photos! Another thing is shipping options. My customers should be able to choose between first class, overnight and priority. That would be a life saver around Christmas time. Otherwise app is great.
