I’ve been a Costco executive member for 11 years. These are the 6 products I’ll always buy there.

Although some Costco locations now only sell books seasonally, I’m happy to report that most Costcos near my home in Northern California still have a great, year-round book selection.

I’ve found that books at Costco tend to cost less than those at traditional bookstores, Target, and even Amazon. Many paperbacks are under the $10 mark, and hardcovers often come in well below $20.

Plus, I’ve been able to snag some really gorgeous special editions of books with sprayed edges, embossed covers, and bonus material. And don’t get me started on the decently priced boxed sets — a collector’s dream.

It used to feel like an indulgence to have high-quality bath towels, but thanks to Costco, they’re a cheap addition that makes our bathroom feel like a resort.

I always keep my eye out for the Purely Indulgent 100% HygroCotton ones, which are as affordable as they are soft. I’ve found that ours get even fluffier over time.

I’ve snagged some on sale for as low as $4.99 each — and although I’ve seen bundles from this brand on retailers like Amazon and Walmart, I love that Costco sells individual towels, too.

These go on sale a few times a year at our location, so I always wait to grab a new set when that lovely discount sign appears.

Being a modern adult means actually taking care of yourself. I arm my body with a whole host of vitamins, all of which I buy at Costco.

From prenatal vitamins to fish oil, I’m a big fan of the high-quality, high-quantity options.

I also appreciate that Costco takes the decision fatigue out of vitamin shopping by providing enough options that I can choose the best fit for me, but not so many that I feel overwhelmed.

Being a full-time freelance writer and editor means I’m always on my computer. My work relies on having an updated, efficient computer, quality earbuds, and external monitors.

I love to skip the 30-minute drive and long wait times at the Apple Store and get my devices from Costco instead. It doesn’t hurt that products like MacBook Airs are often cheaper here — I’ve seen some on sale for under $1,000.

Plus, there’s nothing like the convenience of purchasing a new laptop along with a bunch of bananas.

My family has purchased all of our mattresses from Costco. Specifically, we keep an eye out for the ultra-comfortable Sealy Posturepedic ones that our local store stocks a few times a year.

There are plenty of mattresses you can get for an affordable price, but in my opinion, the Sealy Posturepedic mattresses beat their competitors for comfort — and I haven’t found these mattresses at such a low price anywhere else.

At Costco, I’ve gotten one for under $500, whereas on the Sealy website, prices start at around $800.

I love to take a swing through the clothing section a few times a month to see what’s new and what’s on sale. I’ve purchased most of my little one’s longest-lasting pieces from Costco’s famous clothing tables.

I always keep an eye out for baby clothes from Carter’s; I’ve found adorable sets for around $12.
