Use a customer’s objection like a boomerang to prove that they are wrong. When people object to something, turn their own arguments so they go in a circle and come back to them to persuade them. By using what they say, you are saying that they are RIGHT. But here you are attaching your rebuttal to what they say and prove, by association, that what
they want is right.

Example:

• Yes, Mr. Smith it is expensive, but you do not want to buy your wife a cheap
  present, do you?
• Indeed, the house does need work, but as you said, you are a very good do-it yourselfer, aren’t you?
• Certainly, if you do not have the money today, we can arrange for the order to start tomorrow!
