Selling on Vinted is an experience verging on absurdity.
If a size is given why on earth are people asking for the measurements. Do they do the same when buying on line? I don't think so.
Items are sold at a pittance and still buyers want to negotiate the price arguing for 5Euros less on a price of 20Euro. It costs me more to sell an item on Vinted (the back and forth of messages, printing the label, going to the drop off point) than to make a seasonal trip it to a second-hand shop where my items will be sold at a far better price, faster and with less hassle. In addition, selling on Vinted takes forever, in the meanwhile the seller is stuck having to store all these clothes that are not needed anymore.
Frankly, not the best place to sell.
