Clarified to the buyer carolbb9 that no discount could be offered before the trade and suggested to cancel it if she found the price not acceptable. However, she wished to continue and was rude throughout the process.

Carolbb9 was a bidder of "100% 全新Naturehike雙人睡袋" but she did not buy it. After I had accepted her bid in the app, which I cannot undo, she decided not to buy the item when we met in person. The item was later sold to another bidder and we traded successfully, hence the record of "sold".
