Question about Müllex Container

Grüezi, the bucket alone is available for 30.40 (https://www.galaxus.ch/de/s2/product/muellex-behaelter-16l-abfalleimer-7358503) and the lid for 17.25 (https://www.galaxus.ch/de/s2/product/muellex-deckel-abfalleimer-7358524). What is your selling point for this item? Thank you very much,
