Sidekick: Add Cart Drawer Upsell

Help me add upsell recommendations to my slide-out cart drawer without custom theme code:

Store name: [YOUR STORE NAME]
Budget: [BUDGET]
Priority: [PRIORITY - e.g. fastest setup / free shipping progress bar / no-reload dynamic updates / mobile design]
Trigger product(s): [TRIGGER PRODUCT]
Products to upsell: [UPSELL PRODUCT 1], [UPSELL PRODUCT 2]

Do the following:


  App comparison - Compare 2-3 top Shopify App Store apps for cart drawer / slide-out cart upsells (e.g. Cart Upsell & Cross-Sell, Vitals, ReConvert Upsell & Cross Sell). For each, list pricing tier and feature coverage: in-drawer upsell slots, free-shipping progress bar, dynamic no-reload cart updates, and mobile behavior.
  Recommendation - Recommend the top pick given my [BUDGET] and [PRIORITY].
  Install - Initiate installation of the recommended app from the Shopify App Store.
  Confirm & next steps - Confirm the install completed and summarize what to configure inside that app: the upsell rule so “[TRIGGER PRODUCT]” recommends [UPSELL PRODUCT 1] and [UPSELL PRODUCT 2], a section heading like “[SECTION HEADING]”, a max of [MAX ITEMS] items shown, the free shipping threshold at $[FREE SHIPPING THRESHOLD], and styling with [FONT STYLE] / [ACCENT COLOR] to match the theme.


Note: what to look for is an app whose drawer upsell updates the cart live (no page reload, no closing the drawer) and hides items already in cart — but the actual drawer behavior, styling, and analytics tracking are configured inside the installed app’s own dashboard, not in Shopify admin theme code.
