Best selling apps?

I would use Merceri but I’ve been banned for a stupid ass reason 😒 people would ask me where I got the product I was selling and just because I said “Facebook” or “Instagram”, they thought I was trying to sell over another app which they don’t allow in order to not lose customers. I had to type it as F B or I G but it was too late at that point 🤷🏽‍♀️ I sold things on EBay and the fees were crazy and ended up selling for less than I paid for them. I’m leaving to the military and need to sell these items because I won’t be home in God knows when so I’d rather have the extra money
