It’s really confusing. I swear they all used to be reusable with refill bottles, then at some point they just changed to disposable.
Honestly, you would think it would be easy to push refillables… like that would sell just fine. My suspicion is, like ink printers, they don’t want people using other liquids.
In the long run the disposable ones work out to be more expensive which means they make more profit.
But it’s hard for the average consumer to notice that because it takes a while to build up the price.
It’s like the difference between paying for a subscription £90 once a year, Vs paying £10 a month, for 12 months.
Obviously you are better off with the £90 option but it feels like a larger amount if you don’t pay attention.
