Is there an APP for special release products?

[hinterlandwine]

Hi @Shopify , we are trying to form a wine club for the really special stuff that only comes out once or twice a year. Right now I just email this specific group when the wine comes out with a link to the product page in shopify. But I would prefer some kind of subscription or automatic pay and ship option. The issue is that some years we do 1 release, sometimes 2 or 3 (max) so paying a fee for an app I'll only use 1-3 times per year doesn't make financial sense. Should we just manually invoice them via shopify? Thoughts?

Thank you!
