StockX strives to deliver your items to you within 7-12 business days. While this may take a little longer than you're used to, since their marketplace deals with high value and rare products, they want to make sure that the items you buy on their site meet their in-house quality standards. Therefore, the platform's buyer shipping time frame takes into account the time it takes sellers to ship their items to them, as well as the time they spend verifying the items at the factory.
