Bulk packs look cheaper, they often aren't. The trick: don't look at the total price, look at the unit price per 100 grams. That's how you spot rip-off packaging and actually save money.
Step by step
Manufacturers hide price increases through psychological tricks: bigger box, less content. Example: 1 kg muesli for 8 € looks pricier than 500 g for 4.50 €. But 500 g costs per 100 g: 0.90 €, while the big pack only costs 0.80 €. Stores are required to show the unit price (usually fine print). Anyone who compares that instead of the total price saves an average of 25%, without sacrificing quality or quantity. Focus on shelf-stable basics with long shelf life, rice, pasta, legumes, flour, coffee, olive oil. That's where the difference between small and bulk packs is often 20-40%. With fresh products, bulk buying only pays off if you're sure you'll use it before it spoils.
Step by step
- Read the unit priceLook at the white price label on the shelf. There's the price per 100 g or liter. Write it down for your favorite item.
- Compare all package sizesNot just 500 g vs. 1 kg, check 3-packs, bulk boxes, and special packs too. Sometimes the mid-size is surprisingly cheaper.
- Check promotional pricesPromos change the rules: a normally pricey pack suddenly cheaper. The comparison changes every day, your notes get outdated fast.
- Check shelf lifeBulk packs only make sense if you'll actually use them. Expired muesli is expensive waste. For couples and singles: small packs often work better.
- Reality-check storage capacityPasta, canned goods, dried fruit: good for storage, bulk makes sense. Fresh products: normal shelf life or split with a friend.
