YOLO has two kinds of shopping.
Finds are products we discover at other retailers. When you click a Find, you leave YOLO and purchase directly from that retailer. Their price, inventory, shipping, return, and customer-service policies apply.
YOLO Shop is reserved for products sold directly through YOLO. Those items will be clearly identified and will use YOLO checkout.
On Sale is a live edit of Finds whose prices have become especially interesting. Sale prices can change quickly, so the retailer’s current price always controls.
