Costco Wholesale revealed its most expensive bargain yet this week -- a $1 million diamond ring.
There's only one of these 6.77-carat rings, which is actually discounted from its $1.6 million value.
The wholesaler has been selling engagement rings and high-end jewelry for several years, having already offered diamonds in the $200,000 to $300,000 range. But this is the most expensive item to date.
Here, then, is a look at some of the other unexpected buys you can find at Costco:
Costco sells the basics for life and death. The wholesaler began selling caskets, perhaps coincidentally displayed right near the checkout aisle, in 2004, before expanding further into the funeral business.
The coffins range from about $1,300 to $3,000, with expedited shipping available is ordered by 2 p.m. EST.
Through Costco's Auto Program, members can buy cars, RVs and even boats, at pre-arranged prices set for members.
The wholesaler works with more than 2,200 dealers around the country. Shoppers can browse cars on Costco's Web site, chose a vehicle and locate a nearby approved dealer.
The authorized dealer then contacts the customer and sets up and appointment. There's no obligation to buy a car using once the appointment is set.
According to Costco's Web site, in the past 12 months 500,000 members used the auto program to buy a car, boat or RV.
Aside from purchasing automobiles through Costco, the company also offers online defensive driving courses, through FirstNet Learnings, as well as auto insurance and boat and RV refinancing, through third-parties.
Buy your small business and personal insurance at Costco? Sure, why not?
Granted, the company doesn't actually provide the insurance directly. Instead, it acts like a middleman to pair members with insurance carriers.
Costco offers healthcare through Aetna and has teamed up with Delta Dental of California to offer group dental plan for families of individuals.
Other health offers include electronic health records and practice management for medical practices.
Outside of health insurance, Costco also works to provide auto and home insurance.
Okay, you can't actually buy a house at Costco -- but the wholesaler can help you secure a mortgage.

The list of lenders includes CapWest Mortgage, RMC Vanguard, West Star, Wyndham, Sterling Savings Bank, Bank of Internet and Real Estate Mortgage network.
