How to save at the market: Learn how to calculate the best cost-benefit ratio instantly

You're standing in front of the grocery shelf, looking at two bottles of olive oil. One is 500ml and costs $8.50. The other is a "Special Offer" 750ml bottle for $12.20. Which one is actually cheaper? If you guess wrong, you're literally throwing money away.

Supermarkets and brands often use "deceptive packaging" to make products seem cheaper than they really are. Larger containers aren't always more economical, and "family packs" can sometimes cost more per unit than standard sizes. The only way to win is to look past the sticker price and calculate the price per unit.

The Smart Shopper Rule: Ignore the total price. Always compare how much you are paying per gram, per liter, or per item. That is the true cost of the product.

Why Mental Math Fails in the Aisle

Brands know that doing division in your head while navigating a busy supermarket is difficult. Is $4.32 for 380g better than $5.10 for 450g? Unless you're a human calculator, it's easy to make a mistake or simply give up and grab the one that "feels" cheaper. Over a month, these small errors can add up to a significant amount of wasted money.
