The Best Items New To Costco To Buy In March 2026

Spring officially kicks off in March, but that doesn't mean you can't start prepping for the season early. If you're a Costco member, the store has tons of spring-centric finds and other goodies to get excited about for the month (as of late February 2026). Costco has changed quite a bit since the '80s, going from a single humble location to worldwide expansion, with over 800 stores spread out across eight countries. Throughout the company's years of growth, the core of the warehouse retail chain has remained solid. Members know they'll get quality products at affordable prices, along with perks like a food court and free samples. 

To help you fine-tune your spring shopping list, we took a look at what's new at Costco in the coming month. Our search uncovered seasonal treats, practical kitchen items, gift baskets, cutting-edge appliances, and more. Remember, Costco's online inventory isn't a one-to-one match with what's inside the warehouse. As a result, several of the items featured here can only be purchased through the Costco website or app, while others can be found inside warehouses and online.
