Why Unit Price Comparison Matters
Bulk buying saves money only when the unit price is genuinely lower and you can actually use the product before it expires. Warehouse clubs and bulk bins often offer 20–40% savings on non-perishables. For fresh produce, however, waste can quickly offset any savings.
Bulk Buying Checklist
Before buying in bulk: ① Is the unit price actually lower? ② Can you finish it before expiry? ③ Do you have storage space? ④ Is quality the same? Meeting all four criteria makes bulk buying a true saving.
