They offer a platform to sell courier label but if you get any issue with postage, then eBay will make it harder. I receantly lost two parcels using a label bought from ebay of Evri but I cannot claim for trouble and inconvenience just as I could if I had bought the courier label directly for the same price.EBay will send you to packlink and packlink will send you to Evri and Evri will send you to eBay.Working together to make a fool
