Magical Product Fees may not work with other Shopify apps that interact with the cart or checkout. This includes bundle apps, other fee apps, and upsell apps.
Always label deposits separately for compliance
Display bottle deposit fees as a clearly labeled, separate line item at checkout and on receipts. This meets regulatory transparency requirements, builds customer trust by showing exactly what they're paying, and makes it significantly easier to track deposits for reporting and audits. Use a clear label like "Bottle deposit" or "Container deposit (CRV)" so customers immediately understand the charge.
