Is There a Similar Haggling Phrase in the U.S.?

In the UAE, especially in Emirates other than Sharjah, we sometimes use the phrase ‘معلوم هذا في شارجة كم؟’ or something similar (Do you know how much this costs in Sharjah?) when haggling to point out that an item is cheaper in Sharjah, which often helps lower the price.
Is there something similar in the U.S.? Do people reference specific cities or states known for lower prices when trying to negotiate a better deal? I'd love to hear your experiences or if there's any equivalent phrase or tactic!
