Avraham accepted Efron’s terms. Avraham paid out to Efron the money that he had named in the hearing of the children of Ches—four hundred shekels of silver at the going merchants’ rate.
English: Rabbi Elazar said: The wicked say much and do not even do a little. Whence do we know this? From Efron. At first it is written “a land of four hundred shekels of silver,” and in the end it is written “Avraham weighed out to Efron the four hundred shekels of silver, current among the merchants.”
On the daf / in context: Bava Metzia 87a uses Efron’s conduct as the classic illustration of one who speaks generously but extracts the full (and heavier) payment when the time comes.

What Is Learned
The wicked inflate their offers and then insist on the full (or greater) amount; Efron’s shift from casual “four hundred” to the heavier commercial shekels is the paradigm.
