Stamp Wishlist & Back In Stock

Stamp is a variant level wishlist. Shoppers save the exact size and color, as a guest or signed in, so save for later works on every page. A Notify me button on a sold out product or variant sends automatic back in stock alert emails, and price drop alerts reach everyone who saved that item. A wishlist strip in the cart brings saved items back at checkout. Reports show wishlist revenue, top saved variants and demand for sold out sizes, so you know what to restock and which sizes to bring back.
