They will all help you stay healthy in the new year.

The holidays are here, and Costco is gifting us with some serious sales this season. Every month, the membership-only store releases a circular of sales on top of already steeply discounted member prices, and this month's list includes products that'll help make meal-prep so much easier.

Costco is slashing prices on all sorts of eye-catching gifts this month, including smartphones, tablets, a slew of vitamins, supplements, and delicious groceries; even a 7-night trip to Bora Bora. (Yes, Costco sells vacations!)

But our favorite items are tools and gadgets that you can use to make healthy eating easier, including a new blender and a set of essential meal-prep containers.

Some of the items on the list are available in store only, and prices and availability vary based on your local store, but if you have an account with the retailer, you should be able to buy a few of these online.

These discounts are valid until Christmas Eve, December 24—but you'll need a membership to cash in on these deals. If you know someone with a Costco membership, though, they should be able to get you a Costco Cash Card, allowing you to shop in store without actually ponying up the $60 needed for an annual membership.

Owning a set of food storage containers is a must for any home cook who hopes to portion out meals for the week (we also have a newsletter to help you do that—sign up here!). Eating a meal-prepped lunch is so much easier when you can simply toss one of these Pyrex containers into your bag (or into one of these functional lunchboxes) and into the dishwasher afterwards. These containers are also safe for the microwave and freezer.
