I'm a Brit who moved to the US and now loves shopping at Costco. Here are 12 things I like to buy.

Rao's marinara is my kids' favorite pasta sauce. It's super tasty and is the perfect accompaniment for spaghetti or penne as a quick, easy meal, especially topped with Parmesan shavings.

It's one of the pricier sauces, so I usually get it from Costco, where a pack of two 28-ounce jars costs $11.89.

It's great to have on hand when I'm cooking in a hurry.

My kids enjoy drinking yogurt-based beverages, like Stonyfield's organic, probiotic strawberry smoothies. They also contain 6 grams of protein.

I'm careful about buying perishable items in bulk, but I know even if I get a big box, they'll be gone well before the expiration date.

A pack of 12 costs $9.89.

Costco is a great place to stock up on sunscreen.

My favorite is Alba Botanica's Hawaiian sunscreen since it's easy to apply, smells divine, and is made without oxybenzone and octinoxate, which can be harmful to coral reefs. It's also biodegradable and cruelty-free.

This water-resistant, SPF 50 spray comes in a pack of two for $17.99, which is cheaper than what I've seen at other retail outlets.

I've always been shocked at the high price of razor blades, but they're much more reasonably priced in bulk at Costco.

This pack of Gillette Venus Comfortglide razors is a bargain, with 12 cartridges plus a handle for $29.99.

Each cartridge has three blades and gel bars with a white-tea fragrance.

Whenever I go to Costco, I stock up on mixers and seltzers, which are great to buy in bulk since they have long expiration dates.

I love Fever-Tree's sparkling pink-grapefruit beverage, which is delicious on its own or as a mixer with gin. You can also combine it with tequila to make a Paloma.

A pack of 12 bottles costs $11.59.

Costco is my go-to place for high-quality hair-styling tools like blow-dryers, straighteners, and curling irons. I keep a look out for what's in stock every time I go.

This fabulous T3 Featherweight StylePlus blow-dryer has five heat options, three speeds, and an ion generator, which is supposed to reduce damage to your hair.

I bought it for $99.99.

I love my kitchen cabinets looking neat and tidy, and I'm obsessed with OXO's SoftWorks pop containers because they look great and stack on top of each other.

It makes much more sense to buy them at Costco to take advantage of wholesale prices.

This nine-piece container set costs $49.99 and comes with a variety of sizes for storing everything from pasta to pretzels.

Toilet paper is much more economical to buy in a pack of 30 than in smaller quantities from the supermarket. Plus you won't run out for a long time.

My favorite is Charmin's ultra-soft, jumbo two-ply rolls, which each have 205 sheets.

A 30-pack costs $29.99.

These ready-made, organic super-smoothie blends are perfect for mornings on the go.

Each pouch contains strawberries, blueberries, bananas, mangoes, kale, and spinach. Simply blend the contents with juice or water for a delicious, wholesome drink.

Each pack costs $10.89 and contains six bags.

You can find everything from freshly made bread and bagels to tasty treats like cookies and seasonal fruit pies in Costco's bakery aisle.

But these delicious butter croissants are a family favorite. For a weekend breakfast treat, I warm them up and serve them with butter and strawberry jelly.

A box of 12 costs $5.99.

Charisma's luxury cotton towels and bath sheets are a great find since they're ultra-soft, fluffy, and huge.

These cozy towels come in an array of shades — including white, gray, ivory, beige, and silver — to match your bathroom's color scheme.

A bath sheet that's 35 by 70 inches sells for $13.99, and you can also find matching hand and bath towels.

I'm a big fan of the lunch-box snacks you can find at Costco, specifically The Froot Thief's fruit whips that come in flavors like mixed berry and strawberry.

These gluten-free snacks are made with real fruit and no added sugar. They are also vegan and GMO-free.

A pack of 20 costs $9.99.
