Run bundles and subscriptions from one place, not two apps side by side. Quantity breaks, BOGO, free shipping and tiered pricing apply themselves in the cart. Sell fixed bundles, variant bundles and multipacks, or let shoppers mix and match across a collection. Then make any of it recurring: subscribe and save, subscription boxes, prepaid and replenishment plans on any schedule, and recurring payments that retry failed charges by themselves. Loyalty rewards give subscribers a reason to stay.
