Why Bulk Buying Household Essentials Saves Money for Groups
Bulk buying household staples like paper towels, laundry detergent, and cleaning supplies can cut costs by 30-50%, per Lifehacker analysis. Costco's 2017 revenues jumped $11B, proving demand for value amid rising prices. Sam's Club offers TP at $1.88/4-pack vs. $3.29 retail--a 43% savings.
Mini Case Study (Lifehacker Co-op): Friends bought a $10.28 Costco oatmeal variety pack (40 packs), split into four boxes of 10 ($2.57 each) vs. $3.99 grocery--saving $5.84 per person. A 36-roll TP pack divided nine ways yields four-roll bundles at half price.
Challenges? Storage and overspending. Solution: Inventory first (LemonBlessings tip). Sustainability bonus: Bulk reduces packaging; bamboo TP and microfiber cloths cut soap use 50% (Agar Cleaning).

Fair Cost-Splitting Strategies for Group Bulk Purchases
Equal splits work for identical use (e.g., $10/person for TP, per Bustle roommates). For income differences, go proportional (SoFi/Junehomes): If incomes are $3K/$4K/$5K, shares are 30/40/30%.
Mini Case (Bustle): Three roommates split utilities $70/person equally; TP $10 each from bulk. Contradictory stories: Equal causes resentment if one uses more; proportional builds fairness.
Junehomes calculator: Input totals, adjust for shares--prevents "who ate the snacks?" fights (Monee app vignettes).
