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 some of the issues can be found here.
This prohibition does not apply to all products 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 (Sunday, May 8). Slower turnover items, such as hard pretzels and pasta, may be purchased four weeks after Pesach (Sunday, May 22).
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 Keytsone-K certified Establishments. This includes the entire supermarket that contains Keystone–K kosher sections (Giant – Wynnewood, Giant – Huntington Pike, House of Kosher, and ShopRite on the Boulevard)

Amazon – is publicly traded and does not use a Jewish supplier. However, they also serve as distributor for many Jewish-owned companies.
If the product says, “ships from and sold by Amazon …” (under the ‘buy now’ button), it is fine. If it is sold by a third party, as many Chometz items are, we cannot verify its status.
