Yeah that could definitely work. We're limited technically at the moment (e.g. can't really extend our platform to do things like that), but hiring a team to enable things like that.

What would be really neat is if we learned exactly how much you need and sent you the right amount at the right time.

Just let me schedule it. Trying to "learn" the right time and amount probably won't work well with such small datasets, and has a high risk of annoying your customers.

At most, send me a reminder email asking if I want to repeat last year's order.
