Hey Just pointing out there, that there is a really good drop shipping platform that has over suppliers with really low prices. Great read about drop shipping. For instance your supplier could run out of stock due to importing problems, warehouse fire or any other problem that could occur. When it comes to making money on your app, your best bet will be to add it to Google Play and the App Store. But the thing is that getting traffic costs money. There is absolutely no reason to do this.
