Deal was closed last month but buyer has not transfer the money as I didnt accept paypal from an account with confirmed address. She did suggest paying by paypal a few times but I'm not too comfortable. Bag cost $1275. Shipping was stated as usd50 with tracking from Singapore. She emailed me today and told me she has made payment using bank transfer. ( after nearly 2 weeks ) But she said she paid me $1500 for the bag in another color. ( She asked me if I could sell her the gold bag at $1275 but I told her I am only willing to sell it for $1500. She didnt confirm with me that she wants it and that was her last email to me before she let me know she made payment ) But now, there's a shipping charge of $50 that she didnt pay and I kindly let her know about this. She replied me and said that I am selling much higher price than other seller for that gold bag already and she doesnt want to pay for the shipping... What shall I do now?
