<P> Chametz may be sold rather than discarded, especially in the case of relatively valuable forms such as liquor distilled from wheat, with the products being repurchased afterward . In some cases, they may never leave the house, instead being formally sold while remaining in the original owner's possession in a locked cabinet until they can be repurchased after the holiday . Modern observance may also include sealing cabinets and drawers which contain "Chametz" shut by using adhesive tape, which serves a similar purpose to a lock but also shows evidence of tampering . Although the practice of selling "Chametz" dates back many years, some Reform rabbinical authorities have come to regard it with disdain--since the supposed "new owner" never takes actual possession of the goods . </P> <P> The sale of chametz may also be conducted communally via a rabbi, who becomes the "agent" for all the community's Jews through a halakhic procedure called a kinyan (acquisition). Each householder must put aside all the chametz he is selling into a box or cupboard, and the rabbi enters into a contract to sell all the chametz to a non-Jew (who is not obligated to observe the commandments) in exchange for a small down payment (e.g. $1.00), with the remainder due after Passover . This sale is considered completely binding according to Halakha, and at any time during the holiday, the buyer may come to take or partake of his property . The rabbi then re-purchases the goods for less than they were sold at the end of the holiday . </P> <Table> <Tr> <Td> </Td> <Td> Wikisource has original text related to this article: Talmud's introduction to checking for chametz and defining or (literally, "light") (Tractate Pesachim 2a) </Td> </Tr> </Table> <Tr> <Td> </Td> <Td> Wikisource has original text related to this article: Talmud's introduction to checking for chametz and defining or (literally, "light") (Tractate Pesachim 2a) </Td> </Tr>
