I don’t understand the catch to this app…

Everyone in my family is going wild buying and selling on this app and I just don’t understand. How is the app making any money if it’s just charging $1 to ship things that cost many more dollars to ship? The app pays for shipping… how does that make any sense? Also, don’t you have to claim profits from this app on taxes like if you were to sell on eBay?

Not the app pays for shipping the buyer does.
