Coffins and caskets
Most people probably don't realize that Costco has an entire funeral category and sells caskets in most states. Beyond caskets, which cost between $949.99 and $2,999.99, the company also sells a variety of urns.
Costco's coffins, sold in partnership with Universal Casket Co., are very well reviewed.
"This purchase took much pressure off the difficult time of dealing with Mom's funeral," reads a review of the solid five-star-rated Mother Casket. "She would have loved it, and it was her wish to do this ... Funeral costs are very high, and this product and the people we dealt with were caring and professional."
Doomsday-prepper food kits
Costco sells a number of food kits for emergency situations, with enough supplies to feed a family of four for up to a year.
"The kits range from $1,000 to $6,000 and include a mix of grains, fruits, vegetables, proteins, and dairy," Business Insider's Hayley Peterson reports.
Most of the items can last 25 to 30 years, with food kits packed with things like freeze-dried broccoli, green beans, dehydrated apples, and instant lentils. The huge packages of food weigh about 1,800 pounds and can be stacked up taller than the average man, according to one customer who reviewed the product.
"Enjoy the comfort in knowing you have the essential foods your family will need to survive an emergency or natural disaster!" Costco says on its website.
African safaris
Costco has a number of vacation packages to destinations such as the Dominican Republic, Hawaii, and Fiji, and even a safari in the South African Savanna.
Packages include airfare and hotels, with different locations offering different perks. A visit to the Alsol Tiara Cap Cana resort in the Dominican Republic includes all meals, snacks, beverages, and minibar access for $509 a night. A trip through Lion World Travel includes a spa treatment, a wine tour, and sightseeing trips with prices starting at $4,399 for a weeklong trip.
Engagement rings
If you're shopping for an engagement ring at Costco, you can choose to spend a lot, with options costing up to $102,999.99.
There are also rings on the less expensive side, such as one choice that clocks in at $779.99.
Costco's engagement-ring business found itself in trouble in 2015, when a judge ruled that the retail chain willfully infringed on Tiffany & Co.'s trademarks by selling rings bearing the jewelry brand's name.
Wagyu beef
Thirteen pounds of Japanese Wagyu New York Strip Loin Roast cost a whopping $1,199.99.
The product description reads:
Our Authentic Wagyu Striploin is artfully marbled, with delicate, yet explosive flavor. Our Striploin is taken from the center of the beef loin, which generates a feeling in your mouth that is one of a kind. As you enjoy each bite, you will experience wonderful waves of buttery, sweet, beefy flavor.
According to customers, the beef is worth the investment, with an average of 4.7 out of five stars.
"Each bite does melt in your mouth and the flavor is intense and rich," one review reads. "Just a few bites will make you feel full and satisfied."
"I had brought this item for my mom['s] 99 years old Birthday Celebration," reads another. "I'm glad I did."
Cars
Costco's car business is thriving, with sales growing by more than 6% in the last year while the industry's sales slumped.
The vehicles are sold through partnerships with more than 3,000 auto dealerships in the US, meaning that, technically, Costco itself does not sell the cars. Instead, the retailer uses the program to attract new members and maintain existing members' interest.
A Costco spokesperson told Business Insider that Costco members save an average of more than $1,000 off the average price of a vehicle when using the program, and members can also get a 15% discount on parts, service, and accessories at participating service centers.
Trips to theme parks
You can find bargains on theme parks, including Walt Disney World, Universal Orlando, Disneyland, and other Disney-guided vacations through Costco. The deals typically combine park tickets with vacation necessities, such as rental cars and hotel rooms.
Costco also offers deals on Disney cruises.
