Buying bargain items in bulk is what Costco is all about, and the retailer never fails to disappoint its customers with new deals each week. Given the amount of savings shoppers pocket, the annual membership fee quickly becomes worth it for most folks. To make sure you’re making the most out of your shopping trips, we’re breaking down all the best things to buy at Costco. With the rows of products in-store and endless Costco online shopping pages, options can get overwhelming fast. Not to worry though, as we’ve done the hard work for you and come up with a complete list of all the best things to buy at Costco. From the famed rotisserie chicken to quality healthy foods and groceries for less, you don’t want to miss out on these Costco must-haves.

1. Rotisserie Chicken

Costco’s rotisserie chicken is hands down an excellent value. Whether you have a big group to feed or you’re trying to prep meals for the week, one buy can go a long way. If you prefer to place an order along with other groceries for delivery, the famed rotisserie chicken is available via Costco’s delivery service partnership with Instacart. With that said, you’ll have to pay a bit more if you order online — it rings up for $4.99 in the store, but is over $6 online. Still, it’s a solid deal that should be at the top of your list.

2. Bacon

Who wouldn’t want a cheap pack of bacon? Costco’s Kirkland store brand is less than $5 a pound, so step up those breakfasts and never look back.

3. Salmon

Grabbing seafood at the grocery store isn’t cheap. In addition to convenience, buying in bulk at Costco guarantees you the lowest prices, and salmon is the perfect example, with a 3-lb. pack coming out to about $10 per pound. Be sure to also browse through the store’s featured offers so you don’t miss out on any seafood savings.


4. Organic Carrots

While this may be a comprehensive guide of what to buy at Costco, produce is not typically your best bet here. No matter how big your family is or how often you eat veggies, it’s better to be conservative with your estimates. Fruits and vegetables go bad more quickly than you think, and there’s nothing more frustrating than stocking up and having to throw most of it away. With that said, if you are shopping for Costco produce, stick with must-have vegetables (over fruit) that have a longer shelf life to avoid throwing spoiled produce in the trash every week. Kirkland (the Costco house brand) carrots are a solid choice since they can last for up to a month if properly stored in the fridge. Plus, organic carrots run for just a little over $1 per pound when you opt for the 6lb bag. And hey, you may even get your squad to make the switch from chip snacking to an option that’s better for them.

5. Frozen Broccoli 

Frozen produce is the other exception to the produce rule. “I’m convinced Costco has THE best frozen broccoli,” Liz Shaw, Nutrition Expert and Author previously stated to NBC News. “Convenience is king in my house and these frozen broccoli florets constantly deliver a delicious, high-quality product without sacrificing any nutrition.” Add the vegetable to your freezer for consistently healthy dishes without having to pay a high price tag. The best part? It can hang in the freezer a lot longer than your standard produce purchase, so you won’t have to worry about using it quickly.
