⚠️ When Single Purchases Are Smarter
Fresh Produce & Perishables
Unless you're feeding a large family, bulk fresh items often spoil before use. Calculate your actual consumption rate before buying bulk fruits, vegetables, or dairy.
Products You Might Not Like
Never buy bulk quantities of new food items, cosmetics, or cleaning products you haven't tried. The risk of disliking the product outweighs potential savings.
Items with Changing Needs
Baby products, pet food for growing animals, or specialty dietary items may change as needs evolve, leaving you with unused bulk inventory.

Watch for Quality Changes
Some products have different formulations or quality in bulk sizes. Always check reviews before committing to large quantities.
Consider Opportunity Cost
