13 Can't Skip New Costco Finds To Add To Your Cart In March 2026

Spring is swiftly on its way, and with it comes fresh opportunities for house cleaning, trying new recipes and flavors, upgrading your appliances, and exploring fun new activities — all thanks to Costco, that is. There are already plenty of must-have items if you're new to the popular wholesale club, but the real steals tend to come seasonally. Costco members are in luck this year the winter winds down to a close in March 2026, as the month is already shaping up to be a standout one for new goods hitting the store's warehouse store shelves and website.

As you may already know, the items specifically available in your local Costco are subject to change, and some brand-new items may only debut in certain locations. That said, we decided to make your March shopping extra easy by narrowing down these top new product finds. Whether you're looking for new cookware, fun snack items, or just some extra help with outdoor fun this year, Costco is worth checking out this season.

You don't even have to make paella with this gorgeous, pre-seasoned carbon steel pan because it's so versatile. But if you're a fan of the hearty Spanish dish, this pan is an easy shortcut for smaller batches (pro tip: cold cooked rice will also help get paella on the table faster). You can throw it in the oven up to a whopping 660 degrees Fahrenheit too, and it's safe for all types of cooktops.

For those who celebrate Easter, the hoppy holiday will be here on April 5, 2026.

Plus that fabric basket could totally be re-purposed to hold the LEGO pieces once they're unboxed.

A nice charcuterie board easily impresses guests at spring gatherings, but actually putting one together can be tedious if you don't already have everything you need.

Four matching serving utensils are also included.

If you have a love-hate relationship with nonstick cookware, it might be time to switch gears and try a newer form of the technology.

Social media's been abuzz the last few weeks over this new Costco product in particular. It's essentially an ube boba milk tea in ice cream bar form, and if you're wondering why ube is so popular, it's largely because it works so well in desserts. This package comes with 12, so it's perfect for sharing or just enjoying yourself all spring long.

Fresh berries, fruit, and veggies are great, but the containers (if they even come in them) are often pretty flimsy. Now you can store things in style both in and out of the fridge with this adorable three-piece stoneware bin set. Available in white and green, these bins are so handy they're also dishwasher and microwave safe.

Purchase over&back 3-piece Multipurpose Berry Baskets for $19.99.

Some cooking efforts call for a griddle attachment rather than a regular grill top, but these can be bulky and annoying to clean. On the other hand, this reversible grill and griddle top rectifies that by being smaller and easier to handle. Conveniently, it can sit on top of either a regular outdoor grill or your stovetop.

Purchase Lodge Cast Iron Reversible Grill/Griddle for $39.99.

A nice fondue set may be best known as that quirky home kitchen gadget everyone showed off at dinner parties in the 1970s, but delicious melty cheese (or warm chocolate) is always in style.

Playing KerPlunk is kind of like Jenga, in which multiple players take turns removing sticks holding up a group of balls in a tube.

Purchase Giant KerPlunk Game for $79.44.

This automatic home espresso machine seems to be as current as kitchen coffee brew tech comes, and it also seems well worth snagging one if you want to feel like you have your very own coffee shop at home. It can even pull cold espresso shots so you don't have to wait for your morning cold brew.

Saffron is a super versatile spice that can be used to level up the flavor, aroma, and presentation of your dishes and drinks.

This jar is a newer product at Costco that's $15 off during March, so now's the time to pounce.

Purchase Organic Full Thread Spanish Saffron for $44.99.

One of the hottest March items at Costco is actually in the food court. This is the brand-new Double Chocolate Mint Sundae, a.k.a. Kirkland Signature's very own take on a Shamrock Shake.
