After making a purchase on grailed for a hoodie in medium size, the seller contacted me 3 days later (even though they claim to ship out items within 24 hours of payment received) and said that they'd run out of that hoodie in medium size and that they only had small and large. Obviously I don't want to wear a hoodie in the wrong size, so I asked him to buy the specific hoodie off of someone else for an increased price and sell it to me at the originally agreed upon price. This hoodie is now discontinued and at the time of purchase the listing was perfectly normal and after the purchase it said that payment had been received and that I bought the hoodie. All other listings for the same hoodie are $20-$45 more expensive than the price I bought it off the seller for. AITA?
