17 Costco Deals That Make a Costco Membership Worth it for Couples

Families love Costco. But does a Costco membership make sense for those who don't have a small army to feed?

In many cases, the answer is "yes." From fruit snacks to razor blades and chicken nuggets, the retailer's inventory of bulk-packaged items offers these couples a great way to save on essentials.

Here are a few of our favorite Costco buys that make couples want a Costco membership.

Costco offers discounted prices on resort getaways at exotic locations that will make it easy to save money on travel.

For example, you can plan a getaway to Fiji and earn special perks if you are on your honeymoon. Or book a trip to Mexico's Los Cabos and earn a $100 resort credit.

Costco's prices on ceiling fans, faucets, and other home improvement items often rival those of competitors such as Lowe's and Home Depot.

Costco carries some of the more common hardware items inside the store, but the retailer has a much wider selection online. And unlike other products in their inventory, you don't have to buy these in bulk.

Since alkaline batteries are so expensive, it only makes sense to buy them in bulk. They don't go bad for a long time, and it's convenient to have them around when you need them.

Don't worry about cheaping out on batteries at Costco: Duracell makes Kirkland Signature batteries.

Costco is a great place to stretch your grocery budget and stock up on food items that don't spoil easily. That is particularly true of those items that are usually expensive, such as maple syrup, olive oil, and real vanilla extract.

Certain dry goods (like quinoa and salt) and canned foods (like albacore tuna) are also a good deal at Costco, and you won't have to worry about using them up quickly before they go bad.

Over-the-counter medicines such as ibuprofen and antihistamines are a great deal at Costco. The retailer carries several of these drugs under its Kirkland Signature label, keeping prices low.

While you'll have to purchase a lot at once, the shelf life of these medicines is usually a year or more. Buying in bulk can make sense if you take the medicines regularly.

If you take a daily multivitamin or a specific vitamin supplement, consider switching to the Kirkland Signature brand to save money.

Buying these in bulk is a boon since you probably take at least one a day. So, they're unlikely to expire before you use them. Costco offers a variety of vitamins in pill and chewable forms. Go ahead and buy the gummies: We won't judge.

One of the things that Costco is most famous for is its $4.99 grab-and-go rotisserie chickens.

You might not be able to eat a whole bird yourself in a single sitting, but these are great for cutting up to add to soups, salads, or in your weekly meal-prepped lunches.

If you can't quickly eat a whole chicken yourself, freeze the rest of the meat for later.

Costco offers good enough deals on dairy items that it makes sense to buy things in the retailer's larger packages and freeze them.

While buying two gallons of milk at a time might not make sense for singles and couples, dairy products such as butter and shredded cheese can be easily divided between the fridge and the freezer.

And if you're a smoothie-lover, you won't have any trouble going through 32 ounces of yogurt.

Do you want to eat healthier but end up throwing away greens that have gone bad before you can eat them? Don't ditch your good intentions.

Costco's freezer section offers a wide selection of fruits and vegetables, many of which are organic. While you might not eat four pounds of broccoli this week, having it on hand in the freezer makes it accessible. And it won't rot before you eat it.

Costco has a surprisingly great selection of basic clothing staples, including dress shirts, slacks, jeans, sports bras, activewear, and underwear.

Occasionally, Costco will carry Skechers, Puma, and other brands of athletic shoes at steeply discounted prices.

You can often find great deals on seasonal clothing, such as quality jackets and swimsuits, although you'll have to move quickly before they sell out.

From laundry soap to disinfecting wipes, Costco has your cleaning supplies covered. You'll find some of the best deals for cleaning products under the Kirkland Signature brand.

Since you don't have to worry about trash bags or dish soap going bad, take advantage of buying in bulk here, regardless of the size of your household.

Not only does Costco have some of the best prices around on contact lenses, but they also offer rebates when you buy more.

Many Costco stores also have an optometrist in the store, so you can get your prescription and contacts at the same location.

Replacing tires at Costco can be a good idea. The retailer prices tires competitively, and the price includes inflation with nitrogen, which retains pressure better than air. You also get installation, balancing, and rotation, and a five-year road hazard warranty.

Buying multiple gift cards at once can mean huge savings, even for small households. Costco regularly runs deals when you buy sets of restaurant, airline, gaming, and other types of gift cards

For example, you might pay $79.99 for $100 worth of Domino's Pizza gift cards. Most come in even smaller increments, so you can use these on dates or for basic purchases or give them away as gifts.

As with over-the-counter drugs, prescriptions are often cheaper at Costco than at a typical pharmacy. Consumer Reports has found that Costco medications can be much cheaper than what you would pay elsewhere, for example.

And here's the best part: You don't have to be a Costco member to have your prescription filled there. You can order online or in the store regardless of membership status.

Costco typically offers great deals on flowers. Where else can you get a 50-stem rose bouquet for around $50?

While they won't have the selection of a typical florist, if you're looking for flowers as a gift or to spruce up your apartment, Costco has terrific prices and high-quality stems.

Gas at Costco is often cheaper than at typical gas stations, making a membership worthwhile for families of one or two.

Depending on how often you fill up, your savings on gasoline purchases alone can cover the price of a yearly Costco membership.

Even if you are part of a small household, a Costco membership can still be a great deal.

Many of the bulk items last a long time, so couples can take advantage of the low prices without worrying about wasting money on purchases that expire too quickly.

And when you shop at Costco, remember that paying with the right credit card can help you earn cash back.
