Many of the country's biggest food makers are telling grocers that that they will have limited quantities of a number of their products, including things like Rice Krispies Treats, Sour Patch Kids, some Ben & Jerry's ice cream flavors, McCormick gourmet spices, and Marie Callender's pot pies because of labor, commodity and transportation constraints throttling supply chains, according to emails viewed by CNN and interviews with grocers. Some suppliers are also telling grocers to cancel their promotions of these items and more over the holidays so these items won't disappear from store shelves as quickly.

These latest limits mean that stores won't have all things for all customers heading into the holidays, and shoppers may not be able to find some of their favorite products, flavors or niche items. But shoppers will still have plenty of options, including most of these companies' core products, which they are prioritizing over their products in less demand — meaning, for instance, that if you're a fan of Ben & Jerry's popular Phish Food, you shouldn't have a problem, but the company's less-well known Cold Brew Caramel Latte might be harder to find.
