grocery-price-book

Use when grocery bills keep creeping up, when you want to know which store actually has the best prices on what YOU buy, or when deciding whether a bulk-club membership pays off — builds a personal price book from receipts (manual entry or receipt-file parsing), computes unit prices across package sizes and stores, tracks price history per item to expose shrinkflation and stealth increases, ranks stores by your-basket cost instead of generic averages, and answers bulk-buy and stock-up questions with real math (cost per serving, shelf-life breakeven, membership breakeven).
