I want to buy some arts and crafts stuff from an American seller on ebay - probably up to £75-£100. Will fit in a package about the size of an average hardback book so not too bulky looking. It will only be worth my while to purchase from the US if I don't get charged anything else. I have heard of people having packages retained by Customs and Excise and only having them released on payment of Custom's Duty.
Anyone got any experience or knowledge of this?
