Edit - just to add to the eBay drama. The 9a I actually sold on eBay (brave, I know given the last sale leading me to this point...). The buyer is reputable, good feedback.
I haven't had payment since Friday. I messaged and said I can't post the item now until Tuesday (if he pays) due to bank holiday here in the UK on Monday.
He replied just now saying he's struggling to pay for it... through KLARNA!! :O
What the hell. I didn't even know that eBay allowed you to buy things with klarna. He basically sent me a screenshot of his issue where the klarna app is basically saying there is some sort of address mis-match. I mean, not my problem!!
Why is everything just so difficult!!!
