Forget Brand Loyalty
To save big at the grocery store, you need to forget brand loyalty. You want to get the best deal for your money, and the items that go on sale or that you have coupons for may not always be made by the same company. For example, one week it might be best to purchase a certain kind of pasta, while the next, you buy a different brand because you're able to stack coupons and get a sweeter deal. If there's an item that you adore and can't imagine switching to another brand, keep a lookout for sales and coupons for your beloved product and buy it in bulk at a low price.
