Three roommates sharing an apartment on Fenwick Street recently agreed on a new system for splitting grocery costs after months of confusion over who owed what. Instead of each person buying separate groceries, they now pool a fixed amount into a shared account at the start of each month, which one roommate manages and uses to buy shared items like milk, bread, cooking oil, and cleaning supplies. Personal snacks or specialty items still get purchased individually and are not included in the shared fund. The roommates use a simple spreadsheet, updated after every shopping trip, to track what was bought and how much remains in the pool, and they review it together every two weeks to catch mistakes early. If the fund runs low before month's end, they split the shortfall evenly rather than letting one person cover the gap. They also agreed that any surplus left over rolls into the next month rather than being refunded, which has reduced arguments about small amounts. One roommate said the biggest benefit has been not needing to ask for repayment after every store run, since the system handles it automatically.
