wow,that's too much. I understand what you feel. I had bad experience too. One buyer make me an offer for my item., i was wait for 24 hrs to accept her offer. i give her 7 days to pay and email ask her that contact me if you need more time. finally, after 2 weeks she email me and said " thanks for accepted my offer however i think if i buy it from my duty fee in my country it will be cheaper so that i do not want it anymore". I email her back and said " it's ok if you do not want it but i need to file dispute to ebay to get my final value fee back.( even though i have to still pay listing fees). I filed dispute for non paying bidder to ebay, i think ebay gave her non paying bidder strike!!.. You are not going to believe this, i relisted my items and she emailed me in the angry way and said" What a pity is this? your item still not sell, You are not understanding people, i told you i do not want it, i can buy it over here in my country cheaper. You said ok but you are still give me strike!..wait and see, i will tell everybody about u!!.... OMG..What did i do wrong? of course i need to get my final value fees back from ebay!!.. I think she should be guilty and responsible to her offer but not paying not me!!!.
