|In addition to the prohibitions of eating and owning chametz during Pesach, there is an additional prohibition of benefitting from chametz that was owned by a Jew during Pesach. This is known as chametz she’avar alav haPesach. A more thorough discussion of this prohibition by Rav Yona Reiss can be found here.
This prohibition does not apply to all products that are prohibited on Pesach. For a detailed list of what products this prohibition applies to see here.
Quick turnover items, such as bread and cake, may be purchased at any major store two weeks after Pesach (Monday, April 19). Slower turnover items, such as hard pretzels and pasta, may be purchased four weeks after Pesach (Monday, May 3).
Food items that only contain kitniyos (“legumes”) may be purchased at any store immediately after Pesach.
The following supermarkets have been approved for purchasing chametz immediately following Pesach. This list is evolving and it is possible that more stores will be added.
All Keystone-K certified Establishments. This includes the rest of the supermarket that contains Keystone-K kosher sections (Giant – Wynnewood, Giant Huntington Pike, House of Kosher, and ShopRite on the blvd.)
