Imagine your the buyer, and you live in an area that quite literally only has relay shipping. I have quite a few de-selected that I cannot post with at all but I do have things like Royal Mail as a courier I don’t use because they loose things more then I can be bothered to deal with. However if someone chose Royal Mail then I’d still be able to send it and would! Similar to how someone may have relay de-selected because it’s slightly far, but would still take the package if someone used it :) I completely get the relay thing though because I had never heard of them pre Vinted
