Shipping charges

[laudy000]

I haven't sold on ebay in a long time and things sure have changed.  My question is How do I combine shipping for buyers that buy multiple items from my auctions at one time?

First you should enable Combined Payments in your Shipping Preferences and set the payment deadline long enough to allow for auctions not ending at the same time.

Then you can either add rules to automate the combined payment and shipping, or put in your listing for buyer to wait for you to send them an invoice.  Unfortunately, many buyers will miss this note.
