I need help configuring three separate bundle offers in my Shopify store, all built around physical products. Each bundle should be fully customizable so shoppers can mix-and-match up to three items from a defined selection before adding the bundle to their cart. Once the bundles are live, I also want a clear “Donate” link (or button) added—ideally on the cart page—so customers can contribute a set or user-defined amount to our cause during checkout. The work includes: • Setting up the three customizable bundles inside Shopify, using either Shopify Bundles, an approved app, or a liquid-based solution that keeps inventory in sync. • Ensuring each bundle’s product page lets customers pick up to three items and displays dynamic pricing. • Creating and styling the donation link so it fits seamlessly with my theme and passes the donation amount through to checkout as a separate line item. Please make sure everything is mobile-friendly, tested end-to-end, and documented well enough that I can tweak products or prices later without coding.
