postage up to the weight of the letter,also base on normal mail or registered letter. I strongthly advice to used registered letter,if buyer ask a normal mail,it is your risk. I don't refund for the lost.
paypal fee add 4.35% for all the payment unless I don't ask it in invoice.
I'll be in Europe since Jan 22th to Feb 13th ,so all the purchase will be shipped after that
