Stamp Wishlist & Back In Stock vs YOYO

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.

YOYO helps you grow revenue per customer with loyalty tools that drive repeat spend. Run loyalty as points, cashback, or store credit so every return is worth more. Memberships and VIP tiers pull shoppers up the value ladder with exclusive rewards. A referral program brings in buyers who already trust the brand. The loop lives in the customer account so they earn, redeem, and track progress in your store. Conversions over vanity metrics. Interface that needs no training. Results you can measure.
