If you are planning to leave your Depop shop unattended for a while make sure you let the community know.
At the moment, the best way to do so is to add a note in your bio, and then turn off instant payments (i.e change the 'Buy' button to the green 'Message' button) for all of your items so to avoid them being purchased while you are away. Check out how you can activate Instant Payment are here.
Once you are back, just remember to set everything back as before.
Happy holidays and see you back soon!
