click your 'my ebay',
click item you want invoice for,
look top of add,
see 'pay for item',
items should show up there on a combined invoice.
If not,
click icon 'updated invioce',
pay, wait,
either, or.
P.S. It is in your best interest to contact seller BEFORE bidding on any item(s), this way you can know all your costs up front, and not catch it in the rear.
