Some questions about selling makes

So i was wanting to sell some of my makes on here but i dont really know how it works… so here are my questions

  1. How do you know if someone has bought it?
  2. How do you get their address and all that to ship?
  3. What happens if they want a refund!?
    Any other tips and advice would be greatly appreciated!

when they are purchasing it they would give you their address, i think to find if someone has brought it you go to your shop manager <3 Im not sure but i dont know if you can get a refund unless the maker says you can ^^
you could always find more in the help center
