The platform organizes promotions into categories such as home and daily goods, mother and baby products, clothing, shoes, accessories, digital products and appliances, food, beauty, sports, and stationery. Shoppers can browse daily bargains, group-buying promotions, flash sales, and coupon offers, with options to sort products and filter by price or promotion type. Youcu APP also promotes savings through personal purchases and sharing, and provides seller promotion sign-up, customer support, order binding, and user help resources.
