I'm a buyer awaiting an invoice

[NiMhurchu]

3 items won in separate auctions from same seller.

Before bidding on anything I messaged the seller and asked if they offered combined postage, it wasn't mentioned on the listing.

The first auction finished 8hours before the other two. I waited to see the outcome of the second and third auctions. I messaged the seller asking for an invoice with combined postage as soon as the third auction ended. Nearly 48hours ago now.
No reply. Just now I messaged again asking for a reply to my original message and included details again.

What can I do if they don't send an invoice?

I specifically bought multiple items to spread the cost of the postage. Do I have an option of cancelling without getting accused of simply not paying?

Did they agree they would combine?

you can ask them to send cancellation requests but if they want to be arsey they can file 3 non payer cases against you and then you won't be able to leave any feedback either.

If they refuse to combine they have to send each item separately and you can pay for each one separately too, so 3 lots of paypal fees for them - not that that is really the point as you wouldn't have bought if you thought they wouldn't reduce postage.

Yes they said they would combine postage when I asked before bidding, just didn't respond to my messages after that.

I will ask to cancel, it's really not worth paying 3x delivery.
Hope they reply!
