Tiny living and Costco seem like they shouldn't go together.

The wholesale store is known for selling items in bulk. Meanwhile, a campervan means limited space.

But Business Insider's Monica Humphries is a sucker for a deal, so she headed to her nearest Costco outside Denver before a two-week trip in a 75-square-foot van.

The two-week road trip would take Humphries through Colorado, New Mexico, Arizona, California, Nevada, and Utah. She knew she needed to stock up on groceries, road snacks, and winter essentials like hand warmers.

To her surprise, she found she could easily fill an entire cart with meals, snacks, and goods that would come in handy for the trip.

Humphries grabbed a cart and one of the first things she added was Liquid I.V. for $22.99.

She often brings packets of the electrolyte hydration mix Liquid I.V. on ski days, backpacking trips, and long days outdoors to keep herself hydrated.

Plus, 24 packets for $23 was a fair price. Later that week, she went on a Target run where 10 packets of Liquid I.V. were being sold for $18.

When mapping out the trip, Humphries planned to get to her campsites before sunset to avoid driving on rough roads in the dark. This meant she would cook most dinners in her van.

When she arrived at Costco, she wanted to find easy, vegetarian meals she could cook. Ravioli fit the bill. The two packages were enough for four meals, and the pasta was delicious.

As Humphries wandered through the aisles, she stumbled upon a French pesto soup by the company Karine and Jeff.

The vegetarian soup cost $13.99 for two jars — enough for four meals. She saw one jar selling for about the same price as two online.

Humphries absolutely loves Dot's Homestyle Pretzels. The pretzel sticks are coated in a savory seasoning, and she can never get enough of them.

When she spotted a 32-ounce bag for only $9.99 at Costco, she was thrilled. The bag wouldn't be too big to store in the cabinets of her van, and she knew it was a snack she'd eat every last crumb of.

Humphries loves Boomchickapop's sweet-and-salty kettle corn, so, without thinking, she grabbed the enormous bag.

While it was a good deal at $5.99 for 25 ounces (a 7-ounce bag at Target costs $3.79), it was far too big to fit in the storage provided in her van.

The large bag couldn't be stuffed into any cabinet, so for the bulk of the trip, it joined Humphries in the passenger seat.
