Question about Aqua Computer SPLITTY9 Splitter for up to 9 fans or aquabus devices

Hello... How can it be that the product costs only 10CHF directly from the manufacturer (Switzerland) and is offered here at 25CHF? https://www.aquatuning.ch/luftkuehlung/luefterzubehoer/21005/aquacomputer-splitty9-splitter-fuer-bis-zu-9-luefter-oder-aquabus-geraete A few percent more is ok (purchase, stock, margin) but something like this? Cheeky. I will return the item.
