הלכה על בבא מציעא 7:5

We should note that Rav Goren concludes that the buyers have a right to be angry at the seller, since he did not act with the highest levels of integrity and morality (see Mishnah Bava Metzia 6:1). Practically speaking, such conduct by a seller is ill-advised, as he will not succeed in building a good reputation if he does not deliver the promised product in the fullest sense (see Mishnah Bava Metzia 7:5, which dictates to beit din to advise someone that even though the Halachah sides with him in his dispute, he damages his marketability due to his less-than-stellar conduct).
