If you're planning a trip stateside soon, having a solid コストコ アメリカ おすすめ list is basically a survival requirement because these warehouses are massive compared to what you might be used to. Walking into a US Costco for the first time can feel a bit like entering a small city where everything is sold by the gallon or the ten-pound bag. It's overwhelming, it's loud, and honestly, it's a lot of fun if you know what to look for.
I've spent countless hours wandering those aisles, and while some things are the same globally, the US selection has some specific gems you won't want to miss. Whether you're living in the States or just visiting with an empty suitcase, here's the lowdown on what actually deserves a spot in your cart.
The Snack Aisle is a Dangerous Place
Let's be real, the snack section is usually the first place things start getting out of control. American snacking is on another level, and Costco leans into that hard.
Dot's Homestyle Pretzels
If you haven't tried these yet, you haven't lived. They're not your average dry, salty pretzel. They're coated in this buttery, garlicky, slightly spicy seasoning that is incredibly addictive. In regular grocery stores, a small bag is pretty pricey, but at Costco, you get a giant bag for a steal. It's a quintessential コストコ アメリカ おすすめ snack that most locals swear by.
Kirkland Signature Praline Pecans
These are dangerous. They're crunchy, sweet, and salty all at once. They're perfect for putting out when friends come over, but let's be honest, you'll probably eat half the jar while watching Netflix. The quality of the pecans is surprisingly high, and they don't skimp on the coating.
SkinnyPop Popcorn
If you want something a bit "lighter" (even though you're buying a bag the size of a beanbag chair), SkinnyPop is the way to go. It's just popcorn, sunflower oil, and salt, but they somehow make it taste better than anything you can make at home. It's a staple in many American households for a reason.
Kitchen Staples and the Kirkland Magic
The Kirkland Signature brand is legendary in the US. Often, the quality is actually better than the "name brands" sitting right next to them on the shelf.
Kirkland Signature Organic Maple Syrup
In many countries, real maple syrup is treated like liquid gold—expensive and sold in tiny bottles. At a US Costco, you can get a full liter of Grade A organic maple syrup for a price that feels like a mistake. It's the real deal, not the flavored corn syrup stuff. If you do any baking or pancake-making, this is a must-buy.
The Pesto Sauce (Tuscano Cantoni)
You'll find this in the refrigerated section. It is, hands down, one of the best pre-made pestos on the market. It's bright green, packed with basil and pine nuts, and tastes like someone's Italian grandmother just made it in the back. I always keep a jar in the fridge for quick pasta nights or spreading on sandwiches.
Grass-Fed Butter and Kerrygold
While Kerrygold isn't a Kirkland brand, Costco sells it in massive four-packs. If you're a fan of high-quality Irish butter, the price difference between Costco and a regular supermarket is wild. It's one of those things where once you switch, you can't go back to the cheap stuff.
Health, Beauty, and Personal Care
This is where you can really save some money, especially on items that tend to be much more expensive in Japan or Europe.
Vitamins and Supplements
The vitamin aisle in a US Costco is staggering. Whether you're looking for Multivitamins, Fish Oil, or Magnesium, the Kirkland versions are usually third-party tested for quality and cost a fraction of what you'd pay at a pharmacy. Just a heads-up: the bottles are huge, so make sure you have enough room in your luggage!
Cetaphil or Neutrogena Packs
If you have sensitive skin, you probably already know about Cetaphil. Costco usually sells them in two-packs of giant pump bottles, often bundled with a travel-sized version. It's much cheaper than buying individual bottles elsewhere. The same goes for Neutrogena Hydro Boost or their sunscreen packs during the summer months.
High-End Skincare Surprises
Keep an eye out for the "treasure hunt" items in the beauty aisle. Depending on the location, you might find brands like Tatcha, SK-II, or La Mer at significantly discounted prices. These aren't always in stock, so if you see them, grab them.
Clothing and Household Finds
You might not think of Costco as a fashion destination, but don't sleep on the middle aisles.
Levi's and Lucky Brand Jeans
It's very common to find genuine Levi's 501s or 511s for around $30. In many other countries, these same jeans go for $80 to $100. They also carry high-quality wool socks (Kirkland brand) that are famous among hikers for being just as good as expensive brands like Smartwool.
The "Red Solo Cups"
It sounds like a cliché from a movie, but the giant packs of red plastic cups are a real thing. If you're hosting a big party, there's no better place to get them. Along those lines, the Kirkland Signature trash bags are actually legendary. They're stretchy, they don't break, and one box will probably last you a year.
Tips for Your US Costco Adventure
Before you go rushing in, there are a few things you should know to make the experience smoother.
- Membership is Global: Did you know your Costco membership from Japan (or anywhere else) works in the US? Just show your card at the door like usual. It's a huge perk that not everyone realizes.
- Payment Methods: In the US, Costco only accepts Visa credit cards. If you have a Mastercard or Amex, you'll have to use cash or a debit card. This catches a lot of people off guard at the checkout line!
- The Food Court: You can't leave without hitting the food court. The $1.50 hot dog and soda combo is an American institution. Also, keep an eye out for the Chicken Bake—it's a creamy, chicken-and-bacon-filled breadstick that is pure comfort food. The menu in the US is slightly different than in Japan, so it's worth a look.
- The "Double Dash": If you're looking for the best deals, check the price tags. Anything ending in
.97is a clearance item and won't be restocked once it's gone. That's where the real bargains live.
Why it's worth the trip
Shopping at Costco in the US is as much about the experience as it is about the products. There's something uniquely American about seeing a gallon-sized jar of pickles or a 50-pound bag of flour. Even if you don't buy the "mega-sized" stuff, the savings on snacks, electronics, and clothing make it a worthwhile stop.
Every time I go, I find something new that I didn't know I needed. Whether it's a seasonal candle that smells like a forest or a pack of tech gadgets, the "treasure hunt" aspect is real. So, take your コストコ アメリカ おすすめ list, grab a giant cart, and enjoy the chaos. Just make sure you have enough space in your car (or your suitcase) to get it all home!
