Cheapest Shipping for Poshmark Sellers
Stop overpaying on shipping for lightweight fashion items
How Shipping Works on Poshmark
Poshmark uses a simplified shipping model: every sale includes a prepaid USPS Priority Mail label at $7.97 for packages up to 5 lbs. The buyer pays the shipping cost, which is deducted from the sale price before the seller gets paid. For items over 5 lbs, the seller pays the additional weight overage. This flat-rate approach is convenient and removes the guesswork, but it means lightweight items like t-shirts, scarves, and accessories are being shipped at the same rate as heavy winter coats. For sellers who handle their own shipping outside of Poshmark's system, there's significant savings to be found.
