StayCart Buy Bar

StickyCart adds a fixed Add to Cart bar to the bottom of every product page. When shoppers scroll past the main buy button, the sticky bar appears automatically—keeping the purchase action always within reach. The bar shows the product name, price, and a customizable Add to Cart button. It detects variant changes in real time, so the price and availability always stay accurate. Fully mobile-responsive, accessible, and compatible with Shopify Dawn and most major themes. No code changes required.
