Basically I ordered DS a toy from ebay, he had been saving up in 10p increments for ages we got it at a great price, item didn't turn up. Cue autistic ds crying and having a meltdown everyday after school for nearly two weeks when I told him the postman hadn't brought it.
Seller asked me to wait in case it came back to her, apparently she gets parcels sent back to her a lot. 
(??????)
Messaged her today and said if you have not had parcel back I would like a refund. Get a message, ooh guess what parcel has arrived with a sticker saying undelivered (I haven't had a card, called local depot to check and asked in person when I picked up another package and nothing there waiting) do I still want it or do I want a refund.
Have explained to her DS is eagerly awaiting it.
It is a heavy toy (not huge in size but heavy). Postage will be more than toy. Do I need to pay her postage again or not? I don't want her losing money but nor do I want to be forking out money unnecesarily. Basically I want to do the right thing but not sure whose place it is to repay for postage.
