Hi. I am in a position to complete my order for donor sperm. However, the ESP has sent a contract for me to sign. Within this contract it says that I will be responsible for any additional charges that may occur during the process of getting the sperm shipped to UK clinic or thereafter. I have been invoiced for the 3 units, pregnancy slot, and the shipment. The contract does not specify the additional charges that may occur during the shipment process. I've financially set aside the charges I have been invoiced for as well as the bank transfer fee. Does anyone have experience of having to pay any additional charges other than the ones mentioned? I don't want it to be the case of there being hidden fees or information that I am not aware of that could potentially occur. Any advice will be greatly appreciated. Thank you in advance.
