Interested in more than one lot? My eBay site is programmed to charge only one of the shipping fees for all of the lots in your shopping cart: the highest single fee listed from among your multiple lots. 

Add as many lots as you wish -- the shipping fee in your shopping cart should not rise. If it does (eBay is sometimes buggy), do not pay the added fee. Instead, click the "request total" link to receive an invoice with just one of the shipping fees.
