I have sent my luggage over by Parcelforce for the past two years. Using their 48 hours service it has cost my about £17 each way to send for a weight up tp 10kgs. When I weighed in last year the weight was just 20grams under the limit. I think you can send more at a higher cost. I take it to my local post office to send and have it delivered to my accomodation. I think you get a discount on the price if you take it to or collect it from a parcelforce depot. Other parcel delivery firms may beavailable.
