Marvin Leonard’s Wholesale Underground Review (5 Pitfalls & Problems with Amazon FBA)

January 13, 2023

The Wholesale Underground course by Marvin Leonard will show you how to sell products sourced directly from suppliers at wholesale prices on the Amazon marketplace. You learn everything you need to run an Amazon FBA business, from finding trustworthy suppliers to winning the Buy Box, and scaling your product listings to other platforms.

It's getting harder to reach a 6-figure income with Amazon FBA in 2023. The problem is that PPC ads are expensive, and the competition is higher than ever. This business model has many moving parts and may not be the best business model for someone looking to make money online full-time.

In this Wholesale Underground review, we'll see if Marvin's strategies adequately combat these difficulties or if his course offers as much knowledge as other courses do. Expensive PPC ads are just one reason I looked for another online business model, which led me to local lead generation. With local lead generation, we rank sites locally without the use of PPC ads. Later in this article, I'll explain why this popular business model is better than Amazon FBA.

Marvin Leonard is not a big time Amazon FBA guru. He appears to have a good online reputation, mainly because of all the students who have found success with this course.

5 Pitfalls and Problems with Amazon FBA

1. Up-Front Costs

Getting started with Amazon wholesale isn't cheap. You're going to have to invest between $5K-$15K to get started between buying your initial inventory, setting up an LLC, buying test orders from several suppliers to see which supplier has the best products, Amazon seller fees, advertising, and more. The startup costs for this business model will set you back thousands of dollars before you see any sales. It will also prevent you from seeing any profits for the few months to over a year. Many people avoid Amazon FBA because of the thousands you have to spend at first.

2. Product Research is Time Consuming

You are always in the search for the next profitable product that will make you thousands of dollars each month. Even if you find a product that sells well, you can't stop looking for the next product. Most products only do well for a month or two and some are seasonal only. Either way, ad exhaustion is inevitable and people will eventually tire of seeing your ads. This forces you to jump back into the search for the next product in the hope you find one that makes you thousands of dollars or more. Product research is time-consuming and one reason you won't earn a predictable income each month. 

3. High Competition

Every day, on average, over 3700 new Amazon sellers join the platform. This makes it harder for you to sell products and will make the bidding wars for the Buy Box. Competing for the Buy Box isn't worth it because to win it, you've got to have the best price. The problem is that everyone keeps dropping their prices and eventually everyone loses money. This increase in competition makes you spend more money and time on perfecting your Facebook ads. If you do private label, you still have to spend time and money on ads that will outdo what the more established brands are doing. Amazon FBA is an uphill battle that will put you down hundreds and thousands of dollars with no guarantee that you'll get sales.

4. Risk Getting Stuck with Excess Inventory

If you don't get any sales, you're going to get stuck with the excess inventory. If you find yourself in this predicament, you will have to either sell your inventory to break even or sell it off at a loss. This is the risk you take when starting this business.

5. Paid Traffic is Expensive

The cost of advertising on social media platforms is rising with each passing year. According to one study, Meta's CPM rose 61% each year in the past few years. Google's CPM rose 75% each year and TikTok 185% each year. The trend is up for the cost of advertising. This rise in ad cost can also be blamed on the rise in competition. 

Who is Marvin Leonard?

marvin leonard

Marvin Leonard is an online entrepreneur whose parents immigrated from Mexico. Therefore, things weren't easy for him growing up since his family had little money. After graduating high school, he went to community college only because he did not know what else to do. While in college, he got into the police academy at 21.

Eventually, he was promoted to detective, which he did for a year. Marvin was making $80K per year at the time and had what most people would call "job security". Still, this wasn't the career he wanted to pursue. Working overtime, weekends, and holidays made him feel like he had no life at all. After coming across a video by Graham Stephan where he spoke about passive income, Marvin was determined to make a change.

More and more, Marvin began consuming content about business. On April 30, 2018, he quit his detective job and got into wholesale. He hasn't looked back ever since. Marvin got his motivation from knowing that he needed to provide for his wife and newborn baby.

Today, he's a successful entrepreneur who has earned over 6-figures on Amazon. The Wholesale Underground YouTube channel has over 14.2K subscribers, but Marvin doesn't post content often. On a video he posted selling his course at a discounted price for Black Friday, he said he was going to post more content about making money online.

Marvin seems to be more focused on helping other people become the best version of themselves. He is more consistent posting content about fitness on TikTok than about Amazon Wholesaling. On his TikTok account, he has over 18K followers.

Amazon Wholesale FAQs

1) How does Amazon wholesale work?

Amazon wholesale works by a seller buying products directly from a manufacturer at wholesale, or at discounted prices, and then making a profit by selling those products at higher prices to customers on Amazon.

2) How much do Amazon wholesalers make?

How much Amazon wholesalers make depends on what products you sell, how much you pay for wholesale items, how much you spend on advertising, and how many people buy your products. The average profit margin for Amazon wholesalers is between 15%-20%.

3) Is LLC required for Amazon wholesale?

An LLC is not required for Amazon wholesale.

4) Why do sellers leave Amazon?

Sellers leave Amazon for several reasons. They find it to be expensive to get started and may not see a fast ROI. They don't understand the rules, have a hard time finding profitable products, underestimated the workload of Amazon FBA, and aren't patient enough with the business model. 

5) Can you start Amazon FBA with no money?

You can't start Amazon FBA with no money because there are several things you need to do before you make a sale that require you to spend some money, such as buying initial inventory, paying Amazon Seller fees, and paying for advertisements. 

6) Which tool is best for Amazon wholesale?

Tools like Helium 10, AMZScout, ZonGuru, and JungleScout are among the best and most popular that will help you run your Amazon business effectively and efficiently.

Is Wholesale Underground worth it?

The Wholesale Underground is worth it if you want to learn how to start selling on Amazon. Marvin has put together a good course that shows you everything you need to know. There isn't anything missing from his program. His product research could have used some more real life examples, but either way, you learn enough and Marvin is active within his Facebook group even though he providing support for his fitness clients. 

Is Amazon wholesale profitable in 2023?

Amazon wholesale is profitable in 2023 if you understand it isn't as easy to make money on Amazon as it was 5 years ago even if you're selling brand name products. Startup costs are high (between $5K-$15K). You're looking at around $5K-$10K to get things started, which includes buying initial inventory, paying for Amazon Seller fees, product samples, advertisements, and more. 

You need to also look for the next profitable product. It can take months before you find it. If you do, you'll then have to create ads to generate traffic and sales. Keep in mind that your first ad may not convert as well as you might want it to. Therefore, you must try different ad formats and split test several aspects of your ads. If you happen to get sales, your profit margins will also be low. This is an expensive, time-consuming activity, though necessary if you want to succeed with paid ads. 

Amazon FBA also requires you to stay up to date with your inventory and pricing your suppliers have. You have to maintain constant communication with them so that you know what you have and how much you're selling it for. If not, you can end up losing out on a lot of money and wasted opportunities. You even have to make sure you send enough products to Amazon's warehouses. If you're running out of inventory, you need to gauge when is the right time to order more.

Another factor that can hold your business back is that Amazon can suspend your account at any time. If you're not paying attention, days can go by without you getting any sales. In essence, you lose money. 

Similar to other online business models, Amazon Wholesaling does work and you can make money, but it offers nothing close to a passive income like local lead generation does. 

Final Thoughts

Local lead generation provides you with several benefits. For one, you're in control of how you run all aspects of your business. You choose the niche to get into, what local business to send leads to and how much they have to pay you each month. 

I rent this lead gen site to my client for $2000 per month. I have been ever since I built, ranked and rented it over 7 years ago. 

Local lead generation

With local lead generation, you also own your lead generation websites. No one can suspend your website and no one can fire you. You can fire your client and if they aren't providing great customer service to the leads you send them, you can start sending the leads to another company who wants more work each month. 

This business model doesn't require you to invest thousands of dollars to get started and there are thousands of opportunities to generate leads in each market. As long as your sites rank at the top of the search results on Google, you will generate leads for your clients.
