Run volume discounts, mix-and-match bundles, and fixed routines on any product page, then test variants head-to-head and let STAKK declare the winner. Discounts apply natively at checkout via Shopify Functions, the storefront widget installs as a theme app block, and post-purchase upsells extend the order on the thank-you page.
