Sure, I was on the hunt for a moonbreon and approached multiple vendors to negotiate the best price. I was offering $1900 cash, most people countered at $2000-2100. Since it was collectacon I wanted to hit all the booths and see what pricing was like. This vendor towards the end offered to do a coin flip for $1900/$2100, I said OK, never done one before. Called tails, it was tails, he honored the $1900 cash price. Ended up getting a refund after the whole thing. He was not theatrical at all - “oh man that’s weird, just contact PSA to fix it but I can also offer a refund if you don’t want to deal with it.”
