If you are OUTSIDE the UK, you will only be charged ONE delivery fee for each order, no matter how many products you order. You will NOT be charged a delivery fee for EACH ITEM.
Also, If the ACTUAL postage charge to your country is LESS than the amount you have paid, you will be refunded the difference after posting. The reason for this, is that Shopify cannot differentiate the weight of a book from the weight of a men's tie; so there is one standard delivery charge paid PER ORDER.
For Example: If you buy 2 books and 1 tie, you will pay ONLY ONE postage charge, and if the actual cost is less after posting, the difference will be refunded.
