Costco just increased its membership prices — here are 8 things that make the annual fees worth it, as an employee

• Costco announced plans to increase membership fees, but shopping at the store still has its perks.
• If you ask me, Costco's gas prices and concierge service are worth the membership.

It's been a long time coming, but Costco finally announced plans to raise its membership fees earlier this month.

Starting September 1, the gold-star card is set to rise from $60 to $65, and the warehouse's executive membership will be $130 instead of $120.

As a Costco employee, I still think there are plenty of perks to having a membership (even if it's going to be a little more expensive). From saving money by bulk-buying groceries to taking advantage of executive membership rewards, there are tons of reasons it's beneficial to shop at the warehouse.

Whether you're on the fence about renewing your account or just curious about maximizing your membership perks, here are eight reasons a Costco card is worth it.

The warehouse has a very flexible return policy on most merchandise

It seems most people have heard of Costco's flexible return policy. The store guarantees customer satisfaction and offers a full refund for most products sold in-store. Even memberships are refundable if customers are dissatisfied.

Because employees can scan customers' membership cards, shoppers don't need to present a receipt to return products.

That being said, there are some exceptions: Costco has a 90-day return policy on select electronics and appliances. Gift cards, tickets, and precious metals are also nonrefundable.

Costco's gas prices are usually pretty cheap

Fuel prices may fluctuate, but you're more than likely to save some cash by pumping gas at Costco. The members-only gas stations offer plenty of pumps staffed with helpful attendants, and some stores even have car washes.

Costco members can pay to pump gas through their physical membership card, on the Costco app, and in some locations, even via a Costco Pay Fob.

At my store, staff members compare warehouse prices to local gas stations weekly.

The executive membership, in particular, offers great perks

Though the new $65 gold-star membership will get you through the doors, it'll still be pretty basic.

On the other hand, the executive membership gives customers 2% cash-back rewards on qualified purchases. The maximum cash-back reward for an executive card is currently $1,000, but once membership costs increase, it's set to shift to $1,250.

This membership option is great for customers who spend at least $62,500 at Costco annually, as they'll earn the maximum cash back.

The food court offers great deals and tasty options

Anyone dining at Costco's indoor or outdoor food courts must have a membership to purchase their meal.

Costco is known for its $1.50 hot-dog-and-soda combo and 18-inch pizzas that cost less than $10.

Buying in bulk can save most households money

Shopping in bulk can seem overwhelming if you don't have a big family to feed. But buying some everyday products in bulk, such as toilet paper, water, paper towels, and toothpaste, can save money in the long run.

The wholesale warehouse usually offers cheaper prices on clothing, electronics, and household necessities than its competitors, too.

I'd say my family of four saves almost $1,000 each year, not including the 2% cash-back rewards I accumulate through my executive membership.

If you're making a major purchase, Costco has a handy concierge service

Are you looking to buy a television, washer, dryer, or refrigerator? Luckily, Costco offers a concierge service on major appliances, computers, and tablets at no extra charge.

The concierge service helps with technical-support issues and provides a two-year manufacturer's warranty extension from the date of purchase on select items.

Some common exclusions, such as physical or liquid damage, apply to these warranties.

Costco's hearing-aid center offers free exams and competitively priced devices

Costco has some of the best deals on hearing aids and accessories I've seen. Most locations even provide free hearing-aid screenings.

Even better, Costco offers a hearing-aid warranty, follow-up appointments, device cleanings, and checkups. Members can make appointments in-store or by phone.

Members have access to useful services and insurance

Costco memberships are great for in-store or online shopping, but cardholders can also use them for perks outside the warehouse.

The warehouse offers a bottled-water delivery service, deals on travel packages, and opportunities for members to save money on home and pet insurance. You can even get discounts on solar-panel installation.

For example, I used Costco Travel — a service with deals on hotels, rental cars, and cruises exclusively for members — to go to Disneyland. I received a $100 gift card to spend on merchandise or food and a $25 Costco gift card that I put toward my rental car.
