Costco is one of those places you walk into thinking you’ll just grab a few things and walk out — no muss, no fuss and no overextending your monthly budget. It’s simply out of the question that you would spend more than a couple hundred bucks, right? Wrong. 

We get pulled in so easily to the money-saving deals that we can’t just walk away. And let’s face it: they are, in fact, great deals. What’s worse (or so much better) are the online deals, and the fact that you can save so much on so many things. 

Just a bit of browsing on the Costco website will reveal the thousands of dollars you can save on furniture, electronics and appliances, and that’s just the tip of the price tag iceberg. But what about the Costco items that start at an incredibly expensive price point? Below are seven of the most expensive items you can find at Costco, but maybe they are things you will find useful, despite the ding they put in your wallet.

Electronics: Sony Bravia Flat Screen TV

• Price: $2,799

You’ve heard the expression go big or go bigger? This 85-inch Sony flat screen at Costco is an excellent example of that. Whether you’re in the market for a new television or you simply like the idea of going bigger, this television will do it for you. 

It’s a smart TV, of course and it also has mini LED, backlighting and even two years of Sony Pictures free with this purchase. You’ll also get a total of five years of warranty coverage when your bundling is done. You won’t have to go bigger for a while after you get this one.

Furniture: Malibu 3-Piece Leather Power Reclining Set

• Price: $5,999.99

Okay, who hasn’t walked past a couch or chair in Costco and decided to have yourself a seat? You’ve done it. We’ve all done it. And for good reason. The furniture is nice and the prices are too. 

Right now, Costco’s website has a three-piece set of leather seats. A sofa, loveseat and recliner with power headrests, for under $5,000. You’d pay closer to $6,000 or more for this set anywhere else. In fact, Costco is even taking $1,200 off the list price if you buy it online. Of course, like most things at Costco, this is only while supplies last. 

Sports and Fitness: Almost Heaven Sauna

• Price: $6,199.99

Have you been thinking of installing a sauna on your property? It’s all the rage right now for its health benefits like muscle recovery, detoxification, increased metabolism and improved sleep, along with, of course, that much-needed relaxation into your life. 

Well, Costco has jumped on this bandwagon and is offering a six-person sauna Outdoor Barrel, for under $6,000. The whole family can get in at the same time.

Home Upgrades: Ecoflow Delta Pro Ultra Whole-Home Power Solution

• Price: $8,999.99

Worried about power outages lately with all the storms, natural disasters and rolling blackouts? We don’t blame you. A lot of people have been investing in generators lately, thanks to recent events. No one wants to be without heat in the winter or AC in a burning summer. Plus, you’ve got to refrigerate and freeze your food at all times to prevent it from going bad. 

That’s why Costco is offering a Delta Pro Power Solution to provide backup to your entire home. It offers 18kWh, 7299W output and 5.6kW solar input. This single unit can power your home for up to a week. If you’ve got $8k to invest, this will definitely come in handy.

Appliances: GE Profile Electric Kitchen Package

• Price: $8,049.96

Why would you buy your appliances anywhere other than Costco? They have amazing guarantees and warranties, superior condition and some of the lowest prices. 

Right now, you can get a superior four-piece package that includes a fridge, range, double wall oven and dishwasher for under $10,000. And they’ll install everything and take your old appliances away for you. You can’t beat that.

Patio, Lawn and Garden: Exaco Riga XL Professional Greenhouse

• Price: $11,999.99

Speaking of being self-sufficient, one of the most expensive items at Costco right now is the greenhouse that will allow you to grow your own food, protected from the weather, in a safe environment. You’ll get 227 square feet of growing space and storage. 

It’s in a cool onion shape to provide maximum strength and you’ll delight in having this space to grow whatever you like. It’s the perfect companion for your battery generator. You’ll be almost entirely self-sufficient. 

Jewelry: Radiant Cut Diamond Ring

• Price: $319,999.99

If you’re looking to impress the one you love, what better way than to purchase the absolute most expensive Costco item — a one-of-a-kind radiant cut 1.54 carat center WS1 clarity, fancy pink Diamond Platinum Halo Ring?

It sparkles so much, she’ll have to keep her hand under her pillow at night. It helps that no one else in the world will have a diamond like this one.
