We highly advise you to receive seller confirmation on Lazada's end before booking PostCo's free returns service. This is to avoid your parcel getting rejected when it is sent back to the seller.
As the approval for returns comes from the online retailer's side, PostCo cannot be held liable for any parcel rejections after they are deployed from PostCo locations.
However, once you have received your seller approval, feel free to make a returns booking and attach your Lazada Returns label securely on your parcel! To learn more about Lazada Returns, click here.
