I have really sensitive skin so wanted to try The Ordinary Azelaic Acid. I only want the small bottle really (in case I react) and don’t want to pay full price of £11.10 for the same reason, so off I trot to Vinted. There was only one person selling it and it was £10 (£11.20 with buyers protection + postage) with 24 likes so I assumed it was the 100ml (RRP £27.40) but she hadn’t stated in the description and one pic was too difficult to read and in the others she had covered the box so I messaged her. Nope….its the 30ml bottle. Anyway it sold over the weekend so maybe I’m just being difficult but I don’t know why anyone would pay more when they could buy it brand new for less and be able to return it??? I get if it’s a rarer item or something out of stock or discontinued.
