Explore the latest shipping updates including our new, Best rate shipping option, changes to USPS rates and tips to avoid extra fees.New! Lower rates with Best rate labels.
Starting July 28, save more with Best rate labels. Items that meet the size requirements (up to 1 cubic foot and longest side under 22 inches) will qualify for lower Best rate pricing across all shipping carriers (USPS, UPS and FedEx) and weight classes. Our Best rate pricing offers an average of 6% savings vs. our current Standard rates.
Best rate is ideal for packages smaller than a shoebox. For larger items, Standard rates will apply and pricing will be based on dimensional weight to help generate an accurate label. See how it works here.
How do you access Best rate labels? Starting July 28, sellers will be prompted to confirm their package size during the shipping selection process when listing an item. If the package is smaller than a standard shoebox or measures under 1 cubic foot with the longest side 22 inches or less, a Best rate will apply.
Is Best rate shipping only for fashion? No. Best rates are available for any listing that meets the size and weight requirements. While it’s a great fit for fashion items, any package that is under 1 cubic foot with a longest side under 22 inches qualifies for Best rates.
