Combined postage changing in checkout

Hi all

I used to buy/sell a lot on ebay, but haven't done so for a few years so I'm still getting used to all the changes.

 

I'm currently trying to figure out how on earth to do a payment on combined items as the postage changes. The seller combined them for me, and the adjusted postage (large satchel) has changed under my purchased items page. So originally it showed the individual post for each item (3 items), but now shows the total plus the combined post, so all good.

But when I click on the 'pay now' button, and go through to the invoice, the items revert back to the three separate lots of postage. So of course when I log into to Paypal, the postage shows as the non-combined total of $28+, rather than the combined total of $13.40.

 

I sent a message to the seller a few days ago, but haven't heard back yet. She definitely changed the invoice from three separate amounts of post to a combined amount, as it changed under purchases when I contacted her to let her know I was finished bidding.

 

Anything I can do, or do I just need to wait until I hear back from the seller?

 

TIA.
