aliexpress.us vs aliexpress.com are two versions of AliExpress, an online marketplace that connects buyers with Chinese sellers. AliExpress.com is the global platform that serves customers worldwide, offering a vast selection of products across various categories. AliExpress.us, on the other hand, is a version of the site tailored specifically for U.S. customers, with pricing in USD and localized shipping options. Both sites offer similar products, but the main difference lies in the shipping options and delivery times, with AliExpress.us providing faster shipping to U.S. addresses.
