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

I’m not sure why Joseph doesn’t just learn Gemora Pesachim and the Shulchan Aruch etc. I think he’s just trying to start a conversation. Everyone agrees that the whole mechiras chometz is a halachic trick. It is truly a ha’ar’oma. Bitul b’alma sagi – from a Torah perspective Bitul is sufficient. All the rest is d’Rabbonon. Don’t forget that we also rent the part of the house / business that the chometz is contained in.
