Alibaba / 1688.com (China)

Alibaba dominates the wholesale world by connecting buyers directly to Chinese manufacturers on the world's largest platform. On 1688.com, its domestic B2B site, prices are 30–50% lower than what the same suppliers charge on AliExpress or Amazon, slashing costs for small business owners sourcing private label goods. Alibaba's direct factory purchasing outperforms #5 Boxed as a cost reduction tool for inventory, enabling margins that bulk-retail models can't match, while Amazon Business often adds 20% more in fees for similar products.
