Juan did an excellent job on our bundle pricing feature. 👏 We tested it today, and after making one small Shopify shipping setting adjustment on our end, everything is working perfectly. The bundle flow looks great, and we're really happy with how it turned out. Highly recommend Juan for anything Shopify related. Solid 5 Stars!
