Now that retailers are accepting preorders for Fallout 4, one superfan has attempted to pay for the game with bottle caps, which are the in-game currency for the post-apocalyptic RPG series.

Reddit user GatorMacheteJr explains:

“Fallout 3 was my favorite game for several years, so I made the rational choice to start saving up bottle caps. Turns out 4.5 years of undergrad and three years in a Master’s program leads to a lot of drinking.”

In all, GatorMacheteJr sent more than 2,000 bottle caps (weighing more than 11.2 pounds) in a box to Bethesda, in hopes that they would accept them as payment for a copy of the game.

Also included in the box was a note to Bethesda’s PR department; you can read it in the gallery below.

It’s not known if the box has reached Bethesda’s offices in Maryland yet or if the company will actually honor the request. GatorMacheteJr says they’ll keep everyone updated.
