When I signed up for this exchange I chose to spend a large amount of credits, since I didn't see a reason not to.

I didn't think about it that much and once I got matched I sent a gift to my giftee, who was a big Tolkien fan; a copy of the game Shadow of Mordor.

A few days later, I noticed a notification in Steam; "1 new gift".

I clicked on it, but got really confused once I saw that the gift, a copy of "Darkest Dungeon" came from the very same person that I'd sent a gift to just a couple of days earlier.

Shocked, I sent him a message where it turned out that there must have been so few people in Sweden who selected that large of a buy-in that we actually got matched with each other, something I thought wasn't even possible.
