A household using about 1 litre a month pays about €72 more a year if it buys Gea 500ml bottles instead of one 1-litre bottle.
Why?
Packaging cost
Smaller packaging costs more per unit to produce, fill and handle.
Lower shelf price
A small bottle looks cheaper on the shelf even when its litre price is worse.
Freshness concern
Some shoppers prefer smaller bottles because they worry a 1-litre bottle may go rancid after opening.
