We don’t have Dash buttons, but we did “subscribe and save” on Nature’s Miracle litter boxes*. Our actual usage, while heavy, doesn’t quite match up with the subscription estimate - so there’s generally a stack of them in the garage and a new box sitting on the stoop.
* Definitely recommend these things. We do try to avoid disposables, but these are recycled and biodegradable, and they really are almost miraculous in their odor suppression. Empty them as usual for a few days, then toss them when they’re too pee-saoked.
