Known as ‘shrinkflation’, it’s a tactic food and beverage manufacturers use to battle inflationary pressures without losing customers.

Finish Quantum Ultimate Pro dishwasher tablets lemon used to come in a packet of 48 but now come in a pack of 46, despite now being $2 more expensive.

Jumpys multipack chicken chips have increased by 30 cents despite having one less pack, and Burger Rings have lost 10g despite getting 20 cents more expensive.

An eight pack of Helga's wraps traditional white had also diminished from 560g to 508g in September 2021 despite staying the same price.

Why do companies shrink products?

Basically, when the cost of production goes up, like it has recently, food and beverage companies try to hide these rising costs by skimming some weight out of their products without altering the price.

Although sometimes manufacturers have other reasons to shrink products - such as changes to regulation that limit the amount of sugar used in products, for example, or dictate what packaging can be used.

Canstar finance expert Effie Zahos said the best way to combat shrinkflation was with unit pricing.

This is when you shop by comparing products, like for like, based on their actual weight.

She said this was easy to do online because most online stores allowed customers to filter unit prices from lowest to highest.
