How to Start Retail Arbitrage on Amazon in 2026 — Step-by-Step

What You Need Before You Start

Starting retail arbitrage on Amazon is genuinely fast to set up — the entire account creation process takes about 30 minutes, and you can be on your first sourcing run the same weekend. Here is the complete list of what you need, in setup order.

Create Your Amazon Seller Account

30 minutes — do this first

1. 1 Go to sell.amazon.com and click "Start selling".
2. 2 Choose Individual plan — free until you exceed 40 sales/month. No monthly fee.
3. 3 Amazon charges $0.99 per item sold on the Individual plan (deducted from payout).
4. 4 Enter your legal name, email, and create a password.
5. 5 Verify your identity: upload government ID and enter bank account details.
6. 6 Add a credit card for Amazon seller fees (charged only if you owe fees).
7. 7 Complete the tax interview — enter your SSN for individual sellers.
8. 8 Approval typically takes 1–3 business days. You'll receive a confirmation email.

Download the Amazon Seller App

5 minutes

1. 1 Search "Amazon Seller" in the App Store or Google Play. Install the free app.
2. 2 Log in with your Seller Central credentials.
3. 3 Tap the camera icon on the home screen — this opens the barcode scanner.
4. 4 Test it by scanning any product in your home. You'll see the current Amazon price, BSR, and estimated profit.
5. 5 The app also shows whether a product is restricted (you can't sell it) or gated (requires approval).

Activate Your BNPL App

10 minutes — optional but recommended

1. 1 Download Afterpay and create an account with your email and debit card.
2. 2 Make a small test purchase under $30 on anything — this activates your account and begins building your limit.
3. 3 Afterpay works at Walmart and Target in-store via the Afterpay Card in your Apple/Google Wallet.
4. 4 Your limit starts at $500–$600 and grows as you make on-time payments.
5. 5 Also download Klarna — activate it the same way. You'll use both once you scale.

Your First Sourcing Run

2–3 hours

1. 1 Go to Walmart, Target, or TJ Maxx. Head directly to the clearance section.
2. 2 Open the Seller App and tap the camera. Scan every clearance barcode.
3. 3 The app shows: current Amazon price, your estimated net profit, and sales rank (BSR).
4. 4 Log potential buys in your phone notes: product name, buy price, Amazon price, BSR, estimated ROI.
5. 5 Don't buy yet — scan 20–30 items and evaluate later using the 4-question test below.
6. 6 Best days: Tuesday or Wednesday morning, when the previous week's markdowns are fresh.

Step 5 — The 4-Question Buy Test

Before putting any item in your cart, run this check. All 4 must pass. If any fail, you pass on the product.

Step 6 — Create Listings and Ship to FBA

1. 1 In Seller Central, go to Inventory → Add a Product. Search by the product's ASIN or UPC.
2. 2 The product listing already exists on Amazon. You're adding yourself as a seller — set your price at or just below the current Buy Box price.
3. 3 Under Fulfillment → Fulfilled by Amazon, select "Amazon will ship and provide customer service."
4. 4 Generate your FBA shipping plan. Amazon assigns you a fulfillment center — print the shipping labels.
5. 5 Label each unit with the FNSKU barcode Amazon provides. Box the inventory with proper padding.
6. 6 Drop the shipment at UPS or FedEx using your pre-paid Amazon shipping labels.
7. 7 Items arrive and go live in 2–5 business days. You're now selling on Amazon.

Step 7 — Monitor and Collect Your Payout

Items sell. Amazon deposits your payout every 14 days by default, or on-demand once you have a sales history. Use Seller Central's Payments dashboard to track your balance.

• Pay your BNPL installment from your Amazon payout immediately when it deposits.
• Calculate your net profit: Amazon payout − inventory cost − shipping cost = net profit.
• Reinvest 80% of net profit into your next sourcing run. Keep 20% as a cash buffer.
• The Starter Kit tracking spreadsheet handles all of this automatically — enter your transactions and it calculates profit, ROI, and monthly totals.

5 Mistakes Beginners Make (and How to Avoid Them)

• Buying gated products
  Always check the Seller App before touching a product. The lock icon means you cannot list it. One gated purchase is a 100% loss on that item.
• Skipping the ROI calculation
  Amazon fees are 30–40% of the sale price for most categories. "It looks profitable" is not a calculation. Run the numbers on every buy.
• Ignoring BSR
  A product with a 900,000 BSR may sit in FBA for months. Start with BSR under 250,000. Slow-moving inventory creates BNPL payment pressure and FBA storage fees.
• Not checking Keepa
  That item showing $45 on Amazon might have been $12 three weeks ago and is returning to that price. Keepa takes 30 seconds and prevents expensive mistakes.
• Starting with too many items
  Your first sourcing run should be 3–8 products — enough to learn the system, not enough to cause serious financial damage if you make mistakes. Scale after your first successful cycle.
