Walmart labels for 3PL orders — ship on Walmart's rates, even when a 3PL packs the box
Ship with Walmart gives you Walmart's negotiated carrier rates, and Walmart regularly adds shipping credits on top. But if a 3PL packs your Walmart orders, a label you buy yourself never reaches them, and they buy their own postage anyway. So you either skip Walmart's rates or pay for shipping twice. Walmart labels for 3PL orders closes that gap: SKU.io buys the Walmart label for each order going to your 3PL, sends it to them with the order, and tells them plainly to ship on it.
