Step 1: When you book the shipment, the shipping fees on the basis of your declared weight is deducted from your prepaid funds.
Step 2: When LSP bills eBay for the AWB as per actual weight /volumetric dimension whichever is higher, EGS bills you as per your billing cycle the fees charged by the LSP in your eBay invoice.
Step 3: EGS will credit the shipping fee amount deducted from your prepaid EGS funds in the same billing cycle which is reflecting in your eBay invoice as a “Wire Transfer”
Step 4: Hence, the net shipping fees payable by you will be only the difference (if any) between your declared weight and LSP charged weight.
