I sent a 14lb. Lego set to my buyer, and paid for a 19lb label to account for bubble wrap and the box itself. I paid $28.00 as suggested on Mercari website and Mercari came back and added a $314.00 overage shipping fee. I called FedEx and they confirmed that it cost $32.80. $3.00 difference to $300.00 is blatant theft. Stay away from this app.
