Smart Shopping Strategies
Buy in Bulk
Warehouse stores (Costco, Sam's Club) offer 20-40% savings on protein staples. Split with friends if quantities are too large.
Check Unit Prices
Always compare price per ounce/gram, not package price. Larger packages aren't always cheaper per unit.
Shop Sales Cycles
Meat goes on sale every 6-8 weeks. Stock your freezer when prices drop. Chicken often on sale Wednesdays.
Store Brands = Same Quality
Generic eggs, dairy, and canned goods are often identical to name brands. Save 20-30% by switching.
Frozen Over Fresh
Frozen chicken, fish, and vegetables are cheaper and last longer. Flash-frozen at peak freshness = same nutrition.
