Can you throw in some extras if I pay this price?
Let me check with my manager and get back if the price works.
I prefer a fair price over haggling for small discounts.
What is your flexibility on bulk purchases?
This price seems high; can we talk about a discount?
I’m interested in a long-term relationship with fair pricing.
What discounts do you offer for bulk orders?
If I buy in bigger amounts, can you give me a discount?
