I am selling subscription protein powders of different flavours. I used paywhirl for the subscriptions. I want to just create a product where the customer will get a "flavour of the month", based on my stock levels. so they don't need to specifically choose a flavour/variant in their subscription which is either the same flavour or they keep needing to login and change it.
Is there an app like that that will be able to keep assigning a random flavour of the month on a subscription?
I would like to understand the use case a little bit more. When would the customer be able to know what the flavor of the month is?
1. Before the flavor of the month is delivered (e.g. the customer knows about the next month's flavor before it is delivered)
2. When the customer opens the package (at delivery)
