I wish I had!
The best system I’ve seen is the NA beer ‘Lucky Saint’. I subscribed to that for a while and it was really easy to skip a week or change delivery day etc… they only had one product type though so probably easier to manage.
I think NewGround might offer something similar although I haven’t bought from them in a while. Origin Coffee also have an app so might offer some level of subscription management.
I guess we’re also talking about the ‘discovery’ style subscriptions though where it’s less about convenience and more about finding new coffee.
Either way I do prefer just finding and purchasing coffee as and when I need it. The discounts for subscribing are also usually pretty negligible.
