eBay operates a global online marketplace connecting buyers and sellers of new, used, collectible, refurbished, and hard-to-find goods. Individuals, small businesses, and professional merchants list inventory across categories ranging from electronics and fashion to auto parts and collectibles. The platform provides search, pricing, payments, shipping, advertising, authentication, seller tools, and buyer-protection services. eBay's marketplace model is especially associated with recommerce and enthusiast categories where selection, condition, and individual listings matter.
