Fair Trade?

This girl had started a topic in "Price Check" and she said that she will be selling all of her gallery items. I mm her and said that I would pay 200k for her love dress. Well she mm me back and said that she wants 600k for it. Then I said that that is really expensive. She goes "Well I am asking for 15k less then everyone else." After that I checked in shop search and there was some for only 200k so I bought one there.
