I'm having a bit of a clear out - mostly baby stuff, clothes and shoes. Some's gone to charity, some I've popped on Ebay. I usually say that I won't post internationally, but obviously forgot on one item - a large baby toy. The winning bidder was someone from Poland who asked me to send her the final 'invoice' with postage added. She won the toy for £5 but postage (just postage, not packaging which I usually cover myself) is coming in at £15.
I sent her an invoice for £20, explaining my mistake and saying that if the postage was too much and she wanted to back out that would be fine. She's now replied saying that she wants to bid on some of my other items and then will pay for everything together - I guess so postage will be amalgamated.
I feel really uncomfortable about this. On a very simple level I just want the toy out of my flat asap because it's BIG and some of my other items aren't going to end their auctions for another week or two. On another - I don't like the idea of sending things overseas. I'll get them tracked but I don't like the idea of risking what will end up being a decent sum of money (to me) to a postal system that I don't know.
However, I feel as though I should agree to her suggestion. It was my mistake and so I should swallow the inconvenience, right? Or would I be reasonable to go back to her and say 'sorry, I actually don't want to send this internationally or wait for payment at all' and risk the bad feedback?
Just to be clear - I don't have any reason to distrust this buyer - she's been on ebay since 2016 and has over 500 ratings, 100% positive, so I don't think it's a scam.
Sorry for the essay! I know it's a massive first world problem but I'm getting disproportionately stressed by it!
