Journeva: Multi Carts & Upsell

Journeva keeps Cartify's core: unlimited named multi-carts shoppers can build, save, and switch, plus share links that rebuild the exact basket for whoever opens them. A slide-out cart drawer adds rewards progress, free gift tiers, in-cart upsells, and add-ons. On product pages, run volume breaks, buy X get Y, and mix and match bundles priced by a Shopify Function. Pro unlocks checkout order bumps and post-purchase offers.
