Ongoing has defaulted to Subscribe & Save for the purchase type.
This helps our merchants showcase their subscription plans without making the shopper click on the Subscription option to see them.
This also helps increase the merchants chances of getting a subscription sale.
Having the Subscribe and Save activated by default is a great way to get shoppers interested in your subscription offerings. It also highlights your discounts in the pricing automatically, and lets shoppers see the different delivery frequencies available.
Subscribe and Save by default can be turned off. This feature is configurable, so you can make it default to the One Time Purchase if you want.
