Buying chametz before Pesach that will not be in your possession over Pesach
Question
There are people selling before Pesach frozen pies of pizza that can only be picked up right after Pesach. You need to pay for them in advance before Pesach. Is it mutar to buy them? If yes, who can sell the chametz to a non-Jew over Pesach? It's not in the buyer's possession and the people with the pizza don't own them now? And you don't know which ones are yours. If it's forbidden, what should one do if he already paid for it? Thank you.
Answer
Shalom!
Thank you for your question.
If you subscribe to selling chametz gamur for Pesach then you may participate in the sale.
The chametz in question should be included in the sellers chametz sale. This is because, in this particular set of circumstances, the chametz in question is the halachic responsibility of the seller.
