Firstly stating no refunds is only for buyer remorse, if a buyer receives a damaged item then paypals refund process over-rules yours.
Secondly in the event of an item received but not as described dispute its one persons word against anothers so paypal ''tend'' to find in favour of the buyer BUT the buyer has to return the item back to you first before you have to refund.
Lastly you may have packaged it very well but that does not mean that it could still not be damaged in transit.
On the Depop website it says sellers don't need to offer refunds if they don't think it's appopriate?
And you don't if the buyer just changes their minds.
Does PayPal overrule Depop?
They are 2 separate companies but you used paypal to accept payment and agreed to abide by their rules when you agreed to their user agreement when you opened an account.
I don't believe that the buyer didn't break the product in the 6 weeks she has had it before she messaged me, and I would lose a lot of money even if she sent it back.
You may well be right, its just one of the risks of being a seller unfortunately. But sometimes when a buyer realises that they have to return the item at their own expense they sometimes change their mind.
AND I did say paypal ''tend'' to find in favour of the buyer,.............its not a given, so you may be lucky.
Unfortunately there are scammers out there.
