Shipping Tips for Online Sellers

Shipping is the part of reselling that quietly eats your profit if you let it. The articles below are written for sellers who ship multiple packages a week and want a workflow that's fast, predictable, and as cheap as it can reasonably be without sacrificing arrival condition. We compare USPS, UPS, FedEx, Royal Mail, Evri, and the platform-specific labels (eBay Standard Envelope, Vinted shipping, Poshmark Canada Post) on actual sample weights and dimensions — not marketing copy. We cover the packaging hacks that survive shipping (bubble wrap, poly mailers, reinforced corners) and the ones that don't, the right way to ship fragile items step-by-step, what to do when a package is lost or damaged, and how to handle the disputes that inevitably come with high-volume selling. International shipping has its own breakdown.
