Yes. In our experience, a customer’s decision to use subscribe and save is a very personal preference. Some products like a 30-day supply of supplements will have an obvious time to repeat order (28 - 30 days) whereas other products like toilet paper can have a more unpredictable purchase cadence (they tend to be shared across the family).
However just because there’s a very defined time to make a repeat purchase like the case of the supplements, it doesn’t necessarily mean a lot of customers will subscribe and save. We have seen data for supplement businesses where SnS is only about 25% of the repeat customer base as most customers prefer to re-order on their own terms.
In the example below, 64% of people who bought twice did so in the first 90 days and the largest number of repeat orders occurred between days 31 - 60 so we would suggest setting up Subscribe and Save for every 60 days to begin with, and perhaps adding one for every 90 days after.
