开门见山法

"Is there any discount？"

"How much discount do you give？"

"Can you cut the price a little？"

"Can I make an offer？"

"Can you make it a little cheaper？"

"Give me a discount."

"How about buying one and getting one free？"

"Come on. Give me a break on this."

拐弯抹角法

"Lower the price and I'll consider it."

"I like everything about it except the price."

直接表达法

"That's a little too much. It's too expensive."

"Hey, don't try to rip me off. I know what this is worth."

"Can you give me a little deal on this？"

强调品质法

"Quality costs money."

利用有效期法

"I've discussed with our team. We can discuss the price further if you're ready to place an order."

记得讨价还价时保持礼貌和专业，并确保理解对方的立场和底线
