Buying fresh fruits and veggies in bulk at Costco can lead to food waste since they can't be stored long at room temperature. Getting them from local farmers' markets or in smaller quantities is often better.
Costco's large spice and condiment jars may lose flavor before you finish them. Consider buying smaller quantities more frequently elsewhere for better freshness and value.
Soda isn't necessarily cheaper at Costco, and buying in bulk can lead to overconsumption. You can find similar or cheaper prices at regular grocery stores.
Avoid large cereal boxes at Costco if you prefer variety. Buying smaller quantities at regular stores is more practical, especially during sales.
While Costco offers bakery products at good prices, they might not taste as fresh, and the quantities can be too much for a single household. Local bakeries may have better-quality options.
