CartBoost adds a slide-out cart drawer to Online Store 2.0 themes using a Theme App Embed. Merchants set a free shipping goal and messages so shoppers see how much more they need to spend. Order bumps can show dynamic bestsellers or mapped offers based on cart products and a price threshold. Settings for colors, thresholds, and bump rules are managed in the app admin. Billing is handled through Shopify.
