Marvin Leonard – The Wholesale Underground

If you’ve been searching for a no-fluff, practical roadmap to building a real wholesale business on Amazon, Marvin Leonard’s “The Wholesale Underground” is probably already on your radar. And for good reason: it’s one of the more focused, step-by-step trainings specifically on Amazon wholesale – not dropshipping, not private label, but buying brand-name products from real distributors and scaling with systems.

In this review, I’ll walk you through who Marvin is, what the curriculum actually covers, what real students are saying, and then show you how TSCourses lets you access this training at the lowest possible cost with instant access – without sacrificing results.

Who is Marvin Leonard – and can you trust him?

Marvin Leonard is not the loudest “guru” on YouTube, but that’s part of his appeal. He built his name in the Amazon FBA space by documenting his journey as a wholesale seller, claiming multi–6-figure results, and then packaging his processes into The Wholesale Underground.

Unlike many generic FBA trainers, Marvin’s content and social profiles focus heavily on wholesale:
• sourcing brand-name products from legitimate distributors
• using 3PL (third-party logistics) centers
• scaling via systems and VA support

Independent reviewers consistently mention that Marvin “knows a lot about wholesaling” and that his approach is especially useful for beginners who want structure instead of scattered free videos. At the same time, he isn’t a massive celebrity in the space, which often means less hype and more practical training.

Inside The Wholesale Underground: what you really get

The Wholesale Underground is hosted on Teachable and delivers a full video-based curriculum with roughly six core modules plus multiple bonuses. Expect around 20 hours of content broken into short, digestible lessons so you can watch, implement, and move forward quickly.

Here’s how the course is structured:

Module 1 – Business Setup and Foundations
You start with the fundamentals: setting up your Amazon Seller Central account, choosing the right entity, understanding Amazon’s rules, and ensuring your business is compliant. For many beginners, just getting this right saves weeks of confusion and costly mistakes.

Module 2 – The Core Mechanics of Wholesale
This module is all about “how Amazon wholesale actually works.” You learn:
• how the Buy Box really functions
• how to price products strategically
• how to analyze competitors
• which tools to use (like AMZ Scout Pro and RevSeller)
• how to read sales charts and data so you don’t buy dead inventory

This is where you start thinking like a data-driven seller instead of guessing.

Module 3 – Sourcing and Supplier Outreach
Here Marvin shows you how to:
• find and vet legitimate wholesale distributors
• request price lists (and read them correctly)
• run the numbers to decide if a product is worth buying
• avoid common supplier red flags

This is crucial because wholesale lives and dies by relationships and margins. You’re not gambling on trendy products; you’re building repeat orders with trusted suppliers.

Module 4 – Relationships, Negotiation, and Ungating
This is one of the most praised parts of the course in student feedback. Marvin teaches:
• how to write effective emails that get responses
• how to follow up without being annoying
• how to turn a “no” into a “maybe” and then a “yes”
• how to apply for ungating in restricted categories like Toys, Grocery, and Gourmet

Ungating alone can cost hundreds of dollars if you pay a service to do it for you. Students often highlight that learning to ungate themselves more than pays for the course.

Module 5 – Logistics, 3PL, and Inventory Management
Here you learn how to move from “I found a supplier” to “my products are live and selling on Amazon.” Marvin walks you through:
• working with 3PL centers
• prepping and shipping to Amazon FBA
• inventory planning so you don’t run out of stock or over-order

You also get insights into multi-channel fulfillment and how to leverage your existing inventory across other platforms.

Module 6 – Scaling, Systems, and Advanced Topics
The final module dives into:
• hiring your first VA or assistant
• setting up basic systems so you’re not stuck doing everything yourself
• using a website to present yourself more professionally to suppliers
• handling bad buys and minimizing risk

On top of the core modules, you get bonuses like:
• “The Master of Money” – mindset and financial basics for reinvesting profits
• “The Golden Snitch Method” – strategies to uncover profitable products others overlook
• Detailed ungating trainings for specific categories like Toys and Grocery

Real student feedback: what people are actually saying

The best way to evaluate a course is to listen to real students, not just the sales page.

Positive feedback commonly highlights:
• Clear, step-by-step structure: Students say it’s one of the most “comprehensive” wholesale courses they’ve taken, with the entire process broken down from scratch.
• Personal mentorship and support: Many testimonials emphasize that Marvin actually answers questions and provides guidance, which is rare in this space.
• Ungating value: Several students mention saving hundreds of dollars by following Marvin’s ungating methods instead of paying external services.
• Realistic expectations: The course doesn’t promise overnight riches; it sets the expectation that you must put in work and capital.

On the critical side, some reviewers note:
• Not enough depth on product research and niche selection – the focus is more on systems, suppliers, and operations than on advanced product-hunting tactics.
• The official price is high compared to other FBA courses, especially if you’re on a tight budget.
• The private Facebook group can feel quieter than expected, with limited ongoing discussion compared to hyper-active masterminds.

So is The Wholesale Underground worth it?

If you’re an entrepreneur, side hustler, or student who wants to build a **real**, inventory-based Amazon business with brand-name products, The Wholesale Underground gives you a strong, structured foundation in wholesale. It’s especially good if you:
• are tired of speculative private label launches
• want predictable reorderable products
• value clear steps and done-for-you scripts/templates for outreach and ungating

It is less ideal if you:
• want a “quick win” business model with no capital (wholesale needs cash for inventory)
• only care about advanced product research tricks and not systems
• prefer super-active coaching calls and accountability programs over self-paced learning
