I'm ready to commit if you can offer a discount.
If I pay in cash, could you offer a discount?
Is this the fixed price, or is there room to negotiate?
I need to see benefits that justify this cost.
This price seems high; can we talk about a discount?
Can we settle on a price that benefits both sides?
Is this your final price, or is negotiation possible?
Can we find a middle ground on the price?
