This app does little to no help to get your money back from a seller that doesn't ship. They say they are contacting the seller but they only keep giving them more and more time to ship. After 2 weeks no shipped item and No answer from the app, I had to get my credit card to do a charge back. Then the app frowns on me for getting my credit card company involved. Moral of the story, you are on your own when a seller never ships the item. Use a better app for purchasing.
