Wondering if you can do a Costco run on Martin Luther King Jr. Day? Good news: Costco will be open like usual! While they close for big holidays like Thanksgiving and Christmas, MLK Day isn’t one of them. Most other grocery stores, like Kroger, are open too—just double-check your local spot for hours. So if you need those last-minute snacks or supplies, you’re in luck! #Shopping #Costco #MLKDay
