Combine shipping for same eBay bidder?

• best charge cards
• construction equipment shipping
• media buyer
• charged particle

I don't want to charge shipping individually for each item for one buyer, but I don't want to be charged the final value fee for all of the shipping charges if I ship it alltogether.


Basically, how do I combine shipping officially through eBay without using "outside" tactics?
