I've just tried Vinted (with clothing) and I thought, back to Simple Delivery on eBay, all is forgiven.
And as a buyer I get so frustrated with the lack of details, wrong sizing and Vinted's stupid measurements system - across shoulders and length... across shoulders is useful but not until you know the chest measurement.
I couldn't print out my label and arrange collection via Royal Mal - which eBay offers free - and had to go to the post office with a qr code...
