When you have an item you're interested in, you can calculate the shipping prior to bidding - there is a shipping button under the item's description. If you have multiple winning auctions and are combining shipping...the only way I ever find out the combined shipping is when I actually go through with the check-out and pay process (the email they send you will have an option to check out). You are probably aware, but I thought I'd mention that it saves a ton in shipping to combine multiple auctions.
