Vinted states that buyer pays shipping. When tried to print "paid" label - Hermes print in shop machine demanded pay for it. Hermes explained - I need QR code to be able to print in shop for free. Vinted explained they do not send QR codes so I have to pay for shipping. So buyer paid, I paid and they do not do refunds as" nothing was wrong with label". However in settings I can choose to disable Hermes delivery and choose Post office delivery- which is 2x more expensive.
