是否可以增加数量？ 这个量实在太少，如此，价格没有办法调整

I wonder if you can increase the quantity.
The existing quantity is so little that the price can't be adjusted.

Could you increase the quantity? It is impossible for us to adjust the price with current number.

Increase the quantity, OK? This quantity is really too little, so i am sorry to tell you the price cannot be adjusted

Can you increase the number ?
This amount is too small, by that the price can not adjust
