We’ve also been conditioned that buying larger packs is cheaper than buying the smaller packs. Take example the shampoo. The myth is that buying the bigger bottles is cheaper than buying sachets.

Truth of the matter is that it is sometimes cheaper to buy sachets than big packs. This I have proven in buying laundry detergents and condiments like soy sauce and vinegars. Try buying Surf detergents, it is cheaper to buy the small pack than buy the one kilo bag. You can compute this by determining the price per gram of the detergent.

Now who says bigger is cheaper?
