We track staple carbohydrates, fresh produce, proteins, dairy, oils, and pantry basics in sizes people actually buy, noting seasonality and unit conversions. Dietary needs like lactose-free milk or plant-based protein receive practical substitutes. Discounts and multi-buy promotions are recorded carefully so comparisons reflect achievable baskets, not one-day flash bargains.
Rent is captured through standardized proxies by bedroom count and square footage tiers, while utilities combine electricity, heating fuel, water, waste, and baseline internet. We amortize deposits and installation fees realistically. Regional tariffs, climate differences, and building efficiency are considered so month-to-month comparisons remain meaningful and honest.
Getting around and staying well are everyday costs, so we include transit passes, occasional ride-hails, fuel and insurance proxies, over-the-counter medicines, basic co-pay estimates, and essential mobile data. We avoid double-counting by prioritizing typical choices, and document assumptions clearly so communities can question, refine, and own the results.
Open the intake form, photograph a recent receipt, confirm store type, date, and payment currency, then tag a few items with accurate units. Optional notes help, like whether a discount required a membership. Submit, review the preview, and watch your contribution strengthen neighborhood comparisons almost immediately.
We hash contributor identifiers, strip precise addresses, and blur sensitive lines, while keeping enough context to audit. Methods, code snippets, and changelogs stay public. You control what appears, can retract entries, and always know how numbers were built, because confidence grows only with open practice.
Expect a concise digest with trendlines, standout price movements, neighborhood spotlights, and practical swaps worth testing. Early alerts flag shocks, while long-form features celebrate local ingenuity. Occasional polls and office hours invite your priorities, keeping the project accountable, adaptable, and genuinely useful for everyday decisions.
