To use our services you must provide the dimensions and weight to enable us to price up a delivery service for you. It is important when you book a parcel that the information provided is as accurate as possible to avoid the courier charging for excess weight. You can weigh items on bathroom scales, even by standing on the scales with the goods and then without and use the difference. Another tip is to find the item listed online where the dimensions can also be found- eBay is a great tool for this. It is better to over estimate to avoid any additional charges from the couriers.
