3 Incredibly Easy Costco Side Hustle That Can Help You Make Up to $5,000 a Month

In the ever-expanding world of side hustles, taking advantage of Costco’s wholesale prices and huge selection has proven to be a lucrative strategy for people looking to supplement their income. These side hustles are easy to set up, require minimal upfront investment, and can generate an impressive monthly income if done regularly. Here are three profitable Costco side projects that can each potentially bring in thousands of dollars a month:

1. Resale Buzz: Turn Costco Finds into Amazon Gold

Recent TikTok video from Deal Expert Rios (@riostoriches) revealed how he made over $1,000 in just one week by reselling Costco products on Amazon. His strategy is simple: search Costco for bulk discounted items that can be resold at higher prices on platforms like Amazon. The example Rios shared involved Streit’s unsalted matzo crackers, which he bought for $9.89 at Costco and resold on Amazon for up to $26.99, netting a net profit of about $4.67 per box after payment commissions and delivery.

With a Costco membership (available at Gold Star or Executive levels), members gain access to exclusive prices on items with significant resale potential. By keeping an eye on products with wide price gaps between Costco and online retailers, resellers can turn a simple shopping trip into a profitable business. For Rios, this part-time job was especially attractive because of its hands-off nature. After purchasing the crackers, he used Amazon’s Fulfilled by Amazon (FBA) service for packaging and shipping, effectively making money: “Literally in my sleep, over $1,000 in sales in less than a week,” Rios said in the clip. “It’s that simple, man.”

2. Fulfilled by a Merchant (FBM): A Teen’s Path to $5,000 a Month

While reselling through Amazon’s FBA model can be effective, some sellers have even greater success with the Fulfilled by Seller (FBM) model, which gives them complete control over inventory, shipping, and packaging. TikTok user William Rivera told how his younger brother, who was only 15 years old, used FBM to earn up to $5,000 a month. Using only his smartphone and laptop, Rivera’s brother buys items from Costco, handles the fulfillment himself and lists the items on Amazon for resale.

The advantage of the FBM approach is that it allows young entrepreneurs to maintain flexibility in their operations, control inventory levels and customize packaging. Rivera said his brother regularly scans 50 to 100 items per trip to Costco, checking profitability using the Amazon seller app. With this approach, a motivated young entrepreneur can turn a quick trip to the store into a highly profitable side hustle.

The comments section of TikTok videos is full of praise for the young entrepreneur, with many sharing similar success stories. “That’s easy money,” one viewer commented, while another marveled: “$60,000 a year is crazy!”

3. Affiliate Marketing: Turning Your Costco Membership into Passive Income

A third side of the business that is gaining popularity is affiliate marketing. According to a financial influencer DanaPeople with a significant social media following can earn between $3,000 and $5,000 per month promoting Costco products. Affiliate marketing involves promoting products or services and receiving a commission for each sale made through a personalized link. For those who have a following on platforms like Instagram or TikTok, affiliate marketing offers the opportunity to earn passive income simply by sharing content.

Dana explains that anyone with at least 1,000 followers can join the Costco affiliate program and start posting reviews or recommendations for Costco products. Each post contains a unique affiliate link to the Costco website where subscribers can shop. Each sale made through a link earns a commission, which over time can turn into significant income. With enough consistent and engaging content, affiliates can earn a consistent monthly income from Costco sales alone, with some reporting incomes as high as $5,000 per month.

Maximize profit and minimize effort

Each of these additional activities offers unique benefits, from hands-off FBA to FBM inventory control to potential passive income from affiliate marketing. As TikTok user Rios explains, it’s all about identifying profitable products and letting the systems take care of the rest. He notes that simply watching Costco deals and Amazon listings has allowed him to make thousands without much effort.

For those who want to get started, the steps are simple. First, sign up for a Costco membership: Gold Star for $65 or Executive for $130 per year to get access to discounted wholesale items. Then download the Amazon seller app or join the Costco affiliate program to track prices and scan items. Finally, be consistent by visiting Costco regularly, building a following on social media, or refining your resale strategy.

Whether you’re interested in earning money while you sleep, keeping track of your inventory, or earning passive income, Costco offers a number of lucrative opportunities for starting a side hustle. With the right tools and a commitment to consistency, each of these strategies can provide a significant boost to your monthly income.
