The Great Trade Fail

I just tried to trade cards for a copy of jet racing extreme. First they posted a price on my thread with their price (10 cards). Once I added them they started asking for either 25 cards or a tf2 key LOL. I referenced their post on my thread and they went back and changed it from 10 to 12 cards. I said screw it, its only 2 more cards. The person who was trading it had just won it from a giveaway -_- . I would have had no idea but when they pasted the key in chat, the copied the time stamp from the end of the giveaway too LOL. Do you guys have any fun experiences like this?
