USPS faces major financial trouble. Learn how the USPS crisis could impact eBay sellers, Etsy shops, Whatnot streamers, and liquidation resellers who rely on low cost shipping. What Happens If USPS Shuts Down? If the United States Postal Service shut down or significantly reduced operations, the resale industry would face several immediate challenges: Shipping costs for small packages would increase significantly. Many rural sellers could lose access to affordable shipping options. Platforms like eBay, Etsy, and Whatnot would need to rebuild shipping integrations. Liquidation resellers could see profit margins shrink due to higher delivery costs. USPS currently provides the lowest cost shipping option for many lightweight packages. Because of that, the resale economy depends heavily on the postal network remaining stable.
