Any of all of the above. Akin to being grandfathered (but in this case, in a good way!) to a subscription is a cool relic to when Graza was first coming out and it was one of the only sure and easy ways to get the olive oil in general. As it has become more and more available, the subscription actually becomes less and less necessary. But I'm sentimental, especially for products and services I love so the fact that I can change and skip my shipment every time is something I appreciate so I can still enjoy hanging onto these recurring instances. I know this practice is not new and is quite common, but I love how it is handled here. Keep the flexibility available and I'll keep enjoying it's arrival.
