This is a great time of year to stock up on certain groceries.

December is notorious for sales - and the grocery store is no exception. 

Here are some items we all use that tend to cost less between Thanksgiving and Christmas:

* Butter: The price hovers around $4 a box for most of the year but can drop to $1.99 during the holidays. Stock up - it’s freezable.

* Sugar: This staple takes a $1 to $2 price cut in December, especially brown sugar and powdered sugar.

* Crackers: Look for sales on snack crackers and saltines; prices usually bottom out between 75 cents and $1 a box.

* Frozen vegetables: During the holidays, they can drop to as low as 50 cents a bag. 

* Bacon: It usually sells for $2.50 to $6, but it may fall to $1.50 a pack around this time. It freezes like a champ, so buy in bulk. 

* Poultry and pork: Turkey, chicken and ham drop to about .40 cents a pound the week after a holiday.

* Storage supplies: Many plastic bags, wraps, parchment papers, foils and reusable containers are about half price right now.

* Birthday cake mixes: Both everyday and seasonal flavors go on deep sales throughout the holidays. This is the time to buy white, yellow, and chocolate mixes. 

* Canned goods: Chicken broth, soups, green beans, fruit, and pumpkin can be used year round. Look for deals of half off—or more—on anything used in holiday feasts.
