Shopicraft Sticky Add to Cart

When the add-to-cart button scrolls out of view, a slim bar takes its place with the product image, the price and a button, so shoppers can buy from anywhere on the page. It reads the product from the page, so every variant, price and availability is right from the start, and it adds to the cart through your theme's own form. Pick when it appears, where it sits, and one of four looks. The bar can carry a variant picker and a quantity stepper, and a discount badge on sale items.
