Animal Crossing high-speed passenger BrianMp16 is in the process of joining the 1% (in Nintendo terms, at least), as he is about to get enough bells to buy the city's post office model, the most expensive item available in the game. How much does it cost? Audio 999,999,999.

A number of previous players who have acquired a thousand bells have used the starters, but BrianMp16's sales have all been recorded, and based on the ability to guess the prices Tom Nook will be offering turnips based and others items at the store that day.
