求翻译：依據2015年全年度的銷售金額,而且現在提供的價格已經很優惠, 所以明年度的單價仍然維持不變,或許訂單量增加時, 我們可以再重新討論價格是什么意思？

null

By 2015 year annual sales amount, and now provides a price has been very deals, so that the unit remains unchanged, perhaps order quantity increases, we will be able to re-discuss price

Based on 2015 entire year sales amount, moreover the present provides price already very preferential benefit, therefore the duration of next year unit price will still maintain invariably, when perhaps order volume increase, we might again discuss the price

According to the 2015 annual sales amount, and now prices are very reasonable, so next year's price remains unchanged, may order volume increases, we can again discuss the price
