Long story short: got scammed, really wanted to buy another thing that was real, I tried canceling right after I knew it was fake but they gave the scammer a choice and of course they shipped it, causing me to have to waste a $50 gift card because the monkeys at Mercari think that "everyone is a really good person and will never try to scam people". If I ask to cancel an order, then cancel the order. Don't leave it to the hands of the fliping seller for goodness sake.
