人多力量大，求最好的回答方式

首先这个客人质量蛮高的，事都很谨慎 一US新客人7月13号自己找上门，看中我网站一款短裙礼服，简单的款式，留了询盘： we are a wholesale company in USA was looking for new factories of evening dresses and i found you guys,i was looking at the style （YY1） is being around in USA for a while but in the right color we ca still??sale it. I like to know the price of it. the best price we can purchase big quantity. thank you very much. hope to hear from you soon. 报了29USD每件的价格给客人，客人订单是300件，几个颜色。。。免费了样品给客人，客人付了运费，客人还说这一单完还会发些效果图让我新样品 客人到样品后马上说样品质量好，这2天确认订单，但是一拖了半个月，无奈之急打了电话，客人说会马上下单，但是呢，居然2天后回复了： When we first saw this dress on your site we weren't seeing a lot of them around. Now, we are seeing them everywhere and one of our biggest competitors is selling the dress as a closeout for $29. We've discussed it and my husband has has decided we just can't make enough money with this dress. I'm sorry. Thank you for all you he done for us and I'm sure we'll do business in the future. 客人看中的款式YY1本身已经好几年前的款式，销到美国很多件了，客人本身 应该清楚，样品确认前价格也都确认好，以及运费都是确认好，现在说取消，是否我降价2USD到4USD，这个订单会有转机？求高人解答，谢谢
