4 Little-Known Perks of a Costco Membership

Costco has a faithful legion of fans -- otherwise known as members. There are 123 million of them, to be precise. Throughout the years, Costco has added new membership benefits, some less well-known than others. Here are four that members may not realize exist.

1. RV parking

Whether you spend part of each year visiting the highways and byways of North America or you're hoping to rent an RV for your next vacation, it's good to know that some Costco locations allow RVs to park overnight in their lots. Free overnight parking can certainly cut down the cost of travel.

Consider the convenience. You arrive near closing time, pick up all the items you've already burned through or forgotten to bring, and spend the night in a well-lit lot. Granted, pulling an RV into a (typically) packed Costco lot may not be the easiest thing you've ever done, but once the lot clears out, you may even hear the sound of crickets.

Notice we said that some Costcos permit overnight parking for RVs. When a store does not, it's often because local ordinances don't allow it. However, with so many Costcos scattered across the country, you should have options.

The easiest way to determine which Costcos allow overnight RV parking is to check this Costco locations finder. Once you see one near where you plan to stay, call that store and ask to speak with the manager. Once you have them on the line, ask about their overnight policy. If the store does permit overnight parking, ask for permission to stay. According to the Camper Report, Costco has rules for campers, so you may want to ask where you can get a copy of those.

2. Home, auto, renters, and specialty insurance

In the back of our minds, most of us realize that Costco offers insurance, but we're not sure of the details. Partnering with CONNECT, powered by American Family, Costco members receive discounted rates on many of their insurance needs. Beyond the initial discount, CONNECT allows you to add more. For example, you may qualify for a safe driving, multi-policy, or student discount.

And if you're an Executive member, CONNECT sweetens the pot even more by providing you with benefits like roadside and lockout assistance.

At a time when many people are unhappy with the insurance industry, 9 out of 10 members who sign up for CONNECT coverage go on to renew their policy with the insurer.

3. Home and business supplies

While it may occur to you to pick up envelopes and printer paper at Costco, have you ever taken advantage of the low prices on items like checks, ink stamps, and address labels? Many of the supplies you need to take care of business -- at home or in the office -- are available for up to 50% off.

Executive members enjoy an even deeper discount.

4. Floral delivery

Once you factor in delivery costs, sending a lovely bouquet of flowers to someone can cost a small fortune. That's not the case at Costco. Costco's online floral department offers everything from anniversary and graduation bouquets to bulk flowers. And here's where the real savings come in: Delivery is free. The price you see listed on the site, plus tax, is the price you pay.

Few things are more frustrating than typing your credit card number into a florist's site, only to learn that delivery costs nearly doubled your purchase price.

As Costco layers on new perks, keeping track of them may become even more difficult. It's a good idea to check periodically to see if there are any you're not taking full advantage of.
