Redditor GatorMacheteJr loves Fallout more than you do. Don't feel threatened, dude loves Fallout more than any of us. This brave vault dweller collected a grand total of 2,240 bottle caps (around 11 lbs) over the last seven and a half years, and then had the stones to send those to Bethesda as payment for a Fallout 4 pre-order.
His gamble (and very expensive shipping bill) paid off, because he's receiving a copy of the game. According to an email he got from Bethesda, since he was the first person to try this method of payment, they'd honor it (read: don't get any ideas, rest of the internet!). Well done, sir!
