You're enrolled in the global shipping programme so if your buyer is overseas then you won't be able to combine the postage cost I'm afraid, GSP doesn't give you that option. The buyer has to pay for the items individually and you have to package them up individually and post to the GSP hub.
If your buyer is in the UK in the Sold section of My Ebay to the right of the items you should see 'send payment details'.
When you click on that it will take you to an invoice which will list all the items the buyer has purchased.
Change the postage cost in the relevant field, do not click reset, just click on send and the buyer can pay once they receive the invoice.
