15 Best Things to Buy at Costco

Curious what to buy at Costco? While I think some items can be overpriced at Costco compared to grocery store sale savings (especially after using coupons), there are some prices that you just can't beat!

You'll want to start by buying a Costco Membership!

My rule of thumb is to stick to whole foods while shopping Sam's and Costco. However, you can often score great buys on pre-packaged foods, clothing, shoes, gift cards, select toys, household items, and other non-food items especially with instant savings!

But, their regular prices on produce, meat, and dairy products are pretty reasonable, so if you can skip the temptation to buy too much while you're there the membership cost may be worth it. You'll likely find lower prices on even whole foods during a good sale ad at your local grocery store, but Costco's prices on these items are usually fairly competitive. And, they consistently offer good quality at those prices!

Disclaimer: We are all different, and what I think is a decent price may be very different than what you think it is. These are just some guidelines to get you thinking about it, and I was surprised by what I found!
Also note that pricing may be a *wee* bit different now due to increases at the grocery store, so keep that in mind while shopping.

Here are my top 15 best things to buy at Costco:

1. Milk

At $2.93 a gallon, I haven't found another store that regularly carries milk at this price. Occasionally I've seen milk around that price at Aldi, but recently even their milk prices have gone up. If your family drinks a lot of milk each week, a trip once every two weeks might be worth the Costco membership.  This is going to vary quite a bit in pricing depending on what part of the country you're in and if your state has any dairy restrictions.

2. Eggs

The Kirkland Signature Cage Free 24-count AA Eggs are priced at $3.39 at Costco, which equals out to just $1.70 per dozen. While you can usually get eggs a bit cheaper at the grocery store during a sale, this is a nice price for cage-free eggs. And, if you really want to stock up or save a little more money, my store had 5-dozen packs for $7.99 or just $1.60 per dozen!

Note – pricing on eggs has gone up significantly this year, but you're probably still getting a better deal here than most stores!

3. Butter

Butter at Costco comes out to around $2.25 per pound, which is about the price you'd pay during a good sale at the grocery store or Aldi. But since it's their price every day it's worth to buy in bulk and stock up while you're there! And, if you're a fan of Kerrygold Irish Butter, you can two pounds for around $12.99!

---

4. Bananas

At just $1.24 for three pounds of premium bananas, your price comes out to 41¢ per pound. While I've seen prices a little lower than this at the grocery store, this is a pretty great price! Their bananas are always fresh enough to last quite a while (if not, you can always whip up this banana bread recipe!).

---

5. Salad Mix

If you're on the fence about what to buy at Costco – do not skip out on their salad section! While Costco's produce section will vary, my store recently had large 1-pound containers of Organic Spring Mix for just $3.39, which beats the price that you'll regularly find at the grocery store. It's so nice to have on hand if you have a large family who eats a lot of salad!  They also have some of THE BEST salad mix bags around.

---

6. Bottled Water 

If you need to buy water bottles, Costco has a great everyday low price on these. My store has the 40-count packs of 16.9oz water bottles for just $2.99, which comes out to 7.5¢ per bottle. This is so much less than you'd ever pay while you're out!

---

7. Gift cards 

If you're planning to eat out or go see a movie anyways, you might as well enjoy some savings, right? Both Costco and Sam‘s Club offer gift card savings of up to 30% when you purchase gift cards in store or online.

While they vary, you can find nice savings on several great restaurants and even entertainment gift cards like Cinemark! And usually you can find these deals online with a wider selection, too! The best part is you can combine these gift cards with restaurant coupons, which can save you a bundle while eating out.

8. Kirkland Signature Brand items

From paper towels to toilet paper and laundry detergent to trash bags, the Kirkland Signature house brand items are often lower priced than the name-brands with instant savings. And, they work just as well – if not better (in fact, I've heard that many of the Kirkland brands are actually made by BIG brands)!

I love to pick up the Kirkland Signature brand paper towels and toilet paper whenever I'm shopping, as well as fabric softener! If you just need to stock up on household items, reach for the Kirkland brand!

Also, if you use K-Cups, you can usually grab a pretty nice deal at Costco. Costco sells Keurig Organic Medium Roast K-Cups for just $36.99, which is 31¢ per K-Cup. You can often get cheaper deals on Amazon, but if you're running low and want to stock up, grab a box of their K-Cups!

---

9. Frozen Boneless, Skinless Chicken Breasts

Prices of fresh chicken have gone up these days, so if I can grab frozen chicken at a decent price. I found huge bags of Tyson Boneless Skinless All-Natural Frozen Chicken Breasts for just $18.49, which comes out to $1.85 per pound. While it isn't the best price I've ever seen, it is a really good basic everyday price for chicken breasts. It's worth stocking up while you're there to make your life easier!

If you want chicken delivered right to your door, check out this deal we found on Perdue Chicken too!

10. BACON

This one kind of surprised me, but is so worth grabbing when you're there. You can get four pounds of sliced bacon for around $13.49 or just $3.37 per pound. We bought this bacon recently and it was very high quality (not fatty), so I would definitely recommend this one! (Don't forget you can freeze it too!)

---

11. Honey 

I found Wildflower Honey 5 lb containers at Costco for $9.99, which comes out to 12¢ per ounce. I also spotted 3-packs of Organic Raw Honey for just $10.99, which is just 15¢ per ounce – a great every day low price for organic honey! If your family uses a lot of honey for baking or as a natural sweetener, this one's worth picking up.

---

12. Rotisserie Chicken

You can get Costco Rotisserie Chickens for just $4.99 everyday at Costco, which is a fantastic price if you're in a hurry but need an easy meal. They're HUGE – around 3 pounds and already seasoned too. You'll skip paying too much for dinner out, and their rotisserie chickens are delicious with no preservatives or artificial junk. It won't be quite as penny pinched as cooking a whole chicken yourself, but on a busy night that convenience is sometimes worth it!

---

13. Shoes & Clothing

Be sure to check out the piles of name-brand clothes and shoes. I've seen brands like Adidas, Toms, Sperry, and more marked way down compared to retail prices. Plus, I have often found clothing styles marked down to under $5 in select sizes, and the quality is great!

---

14. Charisma Bath Towels

If you're in need of new bath towels or sheets, the Charisma brand is one to get at Costco! You'll find the large bath towels for just $7.99, but they occasionally go on sale and you can get them for a couple dollars less. The quality is fantastic and I love that the hygrocotton makes the towels get softer with every wash.

---

15. Fresh Flowers

If you're looking to brighten someone's day, consider picking up a bouquet of flowers at Costco! My store had beautiful floral arrangements starting at just $9.99 and even had 2-dozen roses for just $17.99. If you have an Aldi nearby, you usually can find smaller bouquets for just $3.99, but if you don't have an Aldi nearby, don't pay floral shop prices for flowers…head to Costco!

---

BONUS: The Costco restaurant.

If you just want a chance to skip cooking, you can't beat Costco's famous 1/4-pound all beef hot dog and 20 ounce drink for just $1.50. They also have huge pizza slices for $1.99 ~ my favorite way to easily feed my kids when we're running errands out and about!

And if you're looking for a sweet treat, grab their huge cups of ice cream for only $1.99 each (they're definitely a shareable size).

While there are a LOT of great deals at Costco, there are also some items you should NOT buy at Costco (the cost to savings just isn't worth it!)

So there's my top fifteen best things to buy at Costco! What would you add to the list? I'd love to hear your thoughts ~ leave a comment to share!
