Reply To: What if I don't want to buy back the chometz from the goy?

You don’t really sell the chometz and then buy it back; that’s just the conversational lashon we use. He gives you a down payment and then you repossess it when he fails to pay the full amount after Pesach. The concept of the goy saying “I’m keeping the chometz” is basically a fantasy dreamt up by people who don’t understand how it works.
