How to Find Replenishables for Amazon Online Arbitrage?

What is Amazon Online Arbitrage?

Before talking about categories and strategies used to identify replenishable products, let’s briefly discuss what Amazon Online Arbitrage is.

In simple terms, arbitrage is a business model where sellers source items from online stores, for example Walmart or Target, and then resell them on Amazon for a profit. This method is entirely online, meaning you don’t need to physically visit different markets. Instead, you use real websites and apps to find profitable products. With the right tools, you can easily find clearance or sale items online. Once a customer buys your product on Amazon, you send it to Amazon’s warehouses or ship it directly if you’re using FBM.

What Are Replenishables in Amazon Online Arbitrage?

In short, a replenishable product is an item that customers purchase repeatedly. These are products that run out, get used often or need replacing, so people buy them again and again.

The idea of replenishable items is powerful, once you discover one, you can restock it, identify steady demand, and keep selling it over time. Be careful not every product qualifies as replenishable. Typically, they are everyday essentials or consumable items likes:

• Grocery and pantry staples
• Health and personal care products
• Clothing basics like socks or undershirts
• Certain toys or hobby supplies

Top Categories for Replenishable Products

In this part, we’re going to highlight some of the most common product categories that are considered replenishables. These lists come from proven, profitable categories based on industry experience.

Grocery and Food

There’s no doubt that everyone needs food on a daily basis. Grocery items are classic replenishable products. Think about packaged foods, snacks, drinks, coffee, and spices. These are consumed regularly and customers keep coming back for them.

 Health and Personal Care

Products like soap, toothpaste, vitamins, medical supplies and personal hygiene items are purchased daily or weekly. Since they run out quickly, they are excellent replenishable options with consistent demand.

 Beauty and Household

Almost everyone uses beauty and household products regularly. Skin care, hair care, cosmetics, cleaning supplies and laundry products are consumed quickly.

Baby and Child

For families with young children, items like diapers, baby wipes, baby formula and children’s vitamins are essentials. Parents purchase these products frequently, so they’re some of the most reliable replenishable categories.

Pet Supplies

Households with pets constantly buy pet food, cat litter, chew toys, grooming products and other accessories. Since pets need ongoing care, these items sell steadily month after month.

Office and School Supplies

Businesses and students often need to restock essentials like printer paper, pens, ink or toner, and notebooks. These are classic replenishable items that drive repeat sales.

Home and Kitchen

This category is broad, but many consumable or replaceable items fit here. Examples include light bulbs, kitchen gadgets, utensils, coffee filters and other everyday essentials that get used up or wear out over time.

Toys and Hobbies

Certain toys and hobby items can also be replenishable. For example, LEGO sets often need replacement pieces and collectible card games may require new packs over time. These create opportunities for repeat purchases in the entertainment space.

All of these categories contain products that people use daily or weekly. Our analysis shows that many items within these categories can sell over 1,000 units per month, proving that they have repeat purchase potential. For sellers—especially new ones—focusing on these replenishable categories can be a great way to build a profitable and sustainable business.

Effective Strategies to Identify Replenishables 

It doesn’t matter if you’re a professional seller or just a beginner, finding replenishable products requires smart research and diligent testing. Here are some effective strategies to help you identify them:

Start with Daily Life

Begin by looking at items that you or your friends buy multiple times a day, week, or month. For example, pasta, light bulbs, toothpaste or printer ink. If you find yourself repurchasing these items regularly, chances are millions of other people are doing the same. It’s a great idea to make a list of such products whenever you encounter them at home or while shopping. Later, if you find these products at discounted prices on different websites, you can buy them and list them on Amazon for profit.

Research Sales Rank and Trends

Another proven method is analyzing sales data. Use apps like Keepa to track a product’s price history and sales rank trends on Amazon. Replenishable product candidates usually show consistent, frequent sales over time. This data helps you avoid one-time fads and instead focus on stable, high-demand products.

Use Online Sourcing Tools

There are many sourcing tools and browser extensions that can automatically search dozens of retail websites for products matching your criteria. These tools save time and help uncover hidden replenishable opportunities. When using this strategy, focus on items with steady. Seasonal products may spike during certain months but then drop off, making them unreliable for consistent income.

Ensure Reliable Availability

Replenishables must be products you can restock consistently. If an item sells out quickly and isn’t available for weeks, it’s not a good choice. The goal is to build long-term sales momentum, which isn’t possible if you can’t maintain stock. Always test suppliers and confirm that inventory can be replenished regularly.

Learn from Communities and Reviews

Online communities, blogs, and forums can provide valuable insights into which products are truly replenishable. Sellers often share their experiences and results, which can guide your product choices. Customer reviews on Amazon also reveal a lot. If people mention they use a product daily or reorder it often, that’s a strong sign it’s replenishable.

Best Tools for Finding Replenishables

To find and source replenishable products, you need to use different tools. At the beginning of your business journey, you can start with free or low-cost resources like Amazon’s own tools, browser extensions or the Seller App. After that, once you gain more experience, spend a few months selling, and become more professional, you can move on to paid tools.

How to Manage Your Replenishable Inventory?

After finding replenishable products, it is very important to make a plan to keep them in stock.

Inventory management means ensuring your products are always available when demand occurs, without overstocking. Here we suggest some best practices for managing replenishable items:

1. Monitor Sales Velocity: One of the most important strategies is to analyze how quickly each product sells, weekly or monthly. For example, calculate the average sales per day or per week. This helps you estimate lead times and set accurate reorder points.
2. Set Reorder Points: A common rule of thumb is to maintain enough inventory for 2 to 4 weeks of sales. When your inventory drops below that level, it’s time to restock.
3. Use Amazon’s Restock Tools: Amazon’s Restock Inventory and Inventory Performance Dashboard are very useful. They analyze your sales history and suggest optimal replenishment levels, helping you avoid both stockouts and excess inventory.
4. Avoid Stockouts: Running out of stock on a replenishable item means lost revenue and potential long-term impact on rankings. Plan to prevent this by keeping a safety buffer or sending shipments early.
5. Diversify Your Sources: Don’t buy items only from one store or website. For each replenishable, have multiple suppliers or marketplaces as alternatives. That way, if one source runs out you have backup options.
6. Regularly Review Your Products: At least once a month, analyze your listings and focus your energy on products with consistently high demand. This ensures your time and money go toward items that drive steady profit.
