Great idea for a thread!
Many of the heimishe canned products and spices are kosher l’pesach year round so I buy them whenever they go on sale. Even if they aren’t on sale it’s definitely easier to spread out the shopping.
If you watch the sales at the grocery chains you can usually get Kedem grape juice at decent prices. They put it on sale purim-pesach time.
Please note that regular A&B gefilte fish is marked chametz.
