问题：最近由于钢材取消了 13%的退税湘信很多人都遇上了要涨价的问题，特别是当客户 问到了 “为什么降价的时候你没有通知我呢?”题的时候我们要怎么回复？
Thank you very much for your kind reply.
Please do trust normally the cost would have stable increasing and decreasing：
1. When I had the slight increasing, I didn't charge from you.
2. When I had the slight decreasing, I didn*t inform you either.
Sure I can totally understand your concerns, as your supplier in the past 10 years, we also supported you many times on the cost again and again, I really hope you could share your best understanding that this time is really important for us. (huge increasing in the cost at least 13%).
I can promise as long as we have any decreasing in the cost I will inform you in the first minute.
If you could support me in this order, sure 1 would feedback you more in the future when you probably need from us, thank you very much.
Looking forward to your kind reply.
