That was definitely the use case for me, specifically for products that I know I can buy in bulk, but don't know exactly how frequently I'm going to need to restock. When my son was younger we had one for baby wipes, and another for nappies. When we got down to the last pack we'd hit the button to have some more delivered, and they'd arrive the next day. For a while I also used one for cat food, but that's got a regular enough consumption rate that the button was replaced by a regularly scheduled order to ensure that we'd have more just before it ran out without having to think about it.
