This might make me sound daft but I didn't realise the seller doesn't get paid on vinted until I click that button, they should make it clearer as I think that would hurry people along. I will certainly click it straight away in future! (I only buy as selling sounds like a faff, particularly if anything like eBay!)
I've had mostly good experiences, apart from the lady who sent me an adidas tracksuit top with clear cigarette burns in who then told me I was too fussy
I tend to only buy new with tags or new without tags since then!
