Sold first item with simple delivery, wanted to check the label and once clicked item is dispatched. No way to reverse it. It was 1C in forecast too cold to send live tropical plant. Ended up messaging the buyer and explaining 😤 there is no option to choose Royal Mail collection which is free! 
I had Royal Mail collecting parcels this morning that I sold elsewhere, I haven’t got a printer then they couldn’t take it. Ended up going to post office with bloody simple delivery eBay parcel 🤯. Lucky only one, I don’t drive! Basically I am screwed. I won’t drag 10 parcels to post office
