After you pay our warehouse will automatically consolidate all your parcels that are submitted in one time into one parcel. We always do our best to make the parcel smaller and lighter to reduce the shipping fee. If the weight or size becomes smaller than how we system charged , the price difference will be refunded to your USGOBUY account the same day we ship your parcel out.  

After you pay we will open, repack and consolidate your parcels for each shipment in order to minimize the weight and save you shipping fee. All the difference will be credited to your e-wallet in your account. In most of the time, the actual amount is much lower than the estimated amount you pay us.
