Question
How do I learn to write?
Answer
Chametz that has a high monetary value (such as liquor which is made from wheat) may be sold rather than discarded. This sale of chametz is conducted via the community rabbi, who becomes the "agent" for all the community's Jews through a halakhic procedure called a kinyan (acquisition). As the agent, the rabbi will sell all the chametz to a non-Jew for a price to be negotiated after the holiday. In the meantime, the non-Jew is asked to put down a small down payment (e.g. $1.00), with the remainder due after Passover. As soon as the holiday ends, the rabbi will contact the non-Jew, to buy the community's chametz back from him. In practice, it is almost inevitably bought back, with a small profit to the non-Jew.
