Flu season is here, and it’s hitting hard—everyone seems to be catching it. Both of my kids came down with it, and I feel like it’s only a matter of time before it gets me too. It’s been a rough couple of weeks, to say the least. Thankfully, I was prepared. I stocked up on everything I needed from Costco because they have the best prices. Here’s a list of must-have items to help you get ready for flu season.
Cough Syrup
Make sure to stock up on Robitussin Cough Syrup. The Costco pack includes two daytime formulas and one for nighttime relief—an absolute lifesaver when that stubborn cough hits. Plus, Costco has the best price on Robitussin, hands down. Skip your local drugstore unless you’re okay with paying double the price.
Organic Bone Broth
When you’re sick, nothing beats a warm, soothing cup of broth. Instead of regular chicken broth, I stock up on organic chicken bone broth from Costco. It’s richer in nutrients, made for sipping, and perfect for staying hydrated and nourished while you’re under the weather.
Cough Drops
You’ll definitely need cough drops for sore throats and persistent coughing. Trust me, they’re a lifesaver. Depending on how many people in your household get sick, you’ll go through a bag faster than you think. You’ll be glad you grabbed the club-size bag from Costco—and the price can’t be beaten.
Applesauce
These applesauce pouches were a lifesaver when my kids had the flu. They’re easy to eat, mess-free, and require no prep—perfect for sick days. And don’t think they’re just for kids—adults will appreciate them too when they need something light and easy to digest.
Tissues
You’ll go through a lot of tissues during flu season—trust me. After caring for two sick kids, we burned through box after box. Do yourself a favor and stock up at Costco. They sell large packs at great prices, so you’ll never run out when you need them most.
Emergen-C
If you’re like me and haven’t caught the flu yet but are surrounded by sick people, it’s smart to boost your immune system. I’ve been drinking Emergen-C daily, packed with essential vitamins to help keep my immune system strong.
Plain Pasta
When your appetite is low, simple, bland foods are often the easiest to tolerate. That’s why I always keep plain pasta noodles in my pantry. They’re quick to prepare and gentle on the stomach when you’re not feeling your best.
Vitamin D
Vitamin D is crucial for a healthy immune system, especially during flu season. I make sure to take mine daily, and of course, I get the Kirkland Vitamin D from Costco. The price is incredibly low.
Coconut Water
Staying hydrated is crucial when you have the flu. That’s why I stock up on Kirkland Organic Coconut Water from Costco. It’s a natural source of electrolytes and a great alternative to sports drinks like Gatorade.
Clorox Wipes
When someone in the house has the flu, you’ll find yourself constantly wiping down surfaces like light switches, doorknobs, and countertops. That’s why Clorox Disinfecting Wipes are a must. You’ll go through them faster than you think, and Costco’s bulk packs are perfect for staying stocked. Check out 26 Things I Never Pay Full Price at Costco
Vitamin C
I also take Vitamin C daily to support my immune health, just in case the flu catches up with me. Costco has the best prices on Vitamin C, and I always go for the Kirkland brand. Check out 21 Delicious High Protein Snacks from Costco to Curb Your Hunger
