Actually, I have already compared the previous quoted price from the plant, and also asked them why the price has been increased sharply. Then, the factory explained to me they made a mistake on previous quotation, and at that time, on one required them to confirm the final price, so they never informed us their quoted price was not accurate.

唉，这样的问题，我这里天天发生！
最讨厌供应商乱报价，下单的时候涨价！

In fact, I have already compared with the previous price quoted by factory and asked why the price is much higher than before. They explained that the previous price they quoted was wrong. But they didn’t inform us since no one asked them to confirm the price again.

In fact , I have checked up the quoted price provided by that factory, and have inquired of them about why the price increasing so much. The factory had explained that they had made a mistake in quoting the price to us ,but none of us confirmed if it was the ture price ,and they thought it was necessary to notice us tha
