- The main idea of this dialogue is <u>the bargaining between both people</u>.
Explanation:
Within the text two people (customer and seller) negotiate closets, first, the customer sees a green one but knowing the price asks for a cheaper one, the seller offers one of fifteen thousand pesos, the customer offers ten thousand pesos and finally, the seller gives the final price of twelve thousand pesos, <u>this whole cycle of situations corresponds to a negotiation regarding the price of the second closet</u>, since unlike the other options given they are not signing a contract, discussing the color of the closet or checking the lowest price of something.
