Scanning here opens Sold Listings. Ignore the white prices; look for green numbers. Tip: If an item has 10 listed but 50 sold in the last month, it's a fast mover (High STR).

Target at least a 50% sell-through rate to keep capital liquid. Always research market values before buying. Ignore active prices; only sold prices matter.

BOLO (Be On The Look Out) for brands that are currently high-profit. Best places: Thrift Stores, Garage Sales, and Estate Sales.

Tip: If an item has 10 listed but 50 sold in the last month, it's a fast mover (High Sell-Through Rate).

What is a good sell-through rate?

A sell-through rate (STR) measures how fast items sell. A good rule of thumb for beginners is to look for items with at least a 50% STR, meaning there are as many sold listings as active listings in the last 90 days.

How to check eBay comps?

  1. Filter by "Sold Items" and "Completed Items".
  2. Sort by "Recent" to see the current market value.
  3. Ignore active prices; only sold prices matter.

Essentials for beginners?

  • Polymailers: Cheap and great for clothing.
  • Bubble Wrap: Essential for breakables.
  • Shipping Tape: Don't use regular scotch tape.

How to weigh packages?

Always weigh your package after it is fully packed. Use a digital scale and round up. Incorrect weights lead to postage adjustments.

What does BOLO mean?

BOLO stands for "Be On The Look Out". It refers to items or brands that are currently high-profit or fast-selling.

Best places to source?

  • Thrift Stores (Goodwill, Savers)
  • Garage/Yard Sales (Lowest prices)
  • Estate Sales (High quality vintage)
  • Media Mail: Cheapest for Books, CDs, DVDs.
  • PirateShip: Never pay post office retail. Use PirateShip.com for commercial rates.
  • Poly Mailers: Don't box clothing. Bag it to keep weight under 1lb.

When scanning books, always check Amazon. Look at the "Best Sellers Rank".


Rule of Thumb:

  • Rank under 1,000,000 = Sells eventually.
  • Rank under 100,000 = Sells very fast.

The Google button is your safety net. Use it to check Retail Prices. If you find a "rare" toy for $10, check Google to make sure Target isn't selling it brand new for $12.

  • UPC-A & UPC-E (Standard Retail)
  • EAN-13 & EAN-8 (International)
  • ISBN (Books & Media)

The Best Free eBay Arbitrage Tool for Resellers

In 2026, sourcing speed is the only metric that matters. Our Free eBay Arbitrage Tool isn't a complex database or a slow API—it's a high-velocity bridge. We've optimized the workflow to be pure Point, Shoot, Go. You scan a barcode, and we instantly provide the launchpads to every major marketplace you need: eBay Sold Listings, Amazon, Etsy, Google Lens, Mercari, and Poshmark. No waiting for internal data to load; we take you straight to the source so you can see live, unfiltered market prices exactly where they happen.

The beauty of this system is its "Rapid Fire" capability. Hit the back button on your phone and you're instantly ready for the next scan. This allows you to process entire shelves of inventory in minutes, not hours. We're here to compete with the bloated, expensive monthly subscriptions by offering a professional-grade alternative for free. Using our integrated profit calculator, this tool ensures that you keep 100% of your profit instead of handing it over to a software company. It's the ultimate utility for the lean, agile reseller who values speed over "magical" estimated scores.

We've also built in total resilience for the real-world conditions of thrifting. If a barcode is scratched or the item is too old for a UPC, our Manual Entry system lets you type in the item name or barcode number. You'll still get the same rapid-fire access to every marketplace, ensuring that your research never hits a dead end. Whether you're a seasoned pro scaling your business or a beginner looking for your first flip, our portal is designed to get you the data you need and get you back to the hunt.

Pro Tip: For better results, pair this guide with our reseller scanner and arbitrage calculator to master your workflow.

Expert Scouting Guide

The Ultimate Sourcing Shortcut

Success in 2026 requires moving faster than the competition. Our tool acts as your personal shortcut to the world's largest marketplaces. Rather than digging through individual apps, we centralize your research. One scan gives you the choice of where to go: Check Amazon for current asking prices, then jump to eBay Solds to see the real demand. It's manual research, but at a tactical speed that feels automated. This hands-on approach is vital because it keeps you connected to the actual market trends instead of relying on a middleman's "estimated" value.

We've designed the interface to be frictionless. No unnecessary records, no complex history to manage—just the information you need, right when you're standing in front of the item.

Our focus is on the fundamental math of a flip. While other apps show arbitrary "scores," we show you the raw heartbeat of the market. This allows you to combine your intuition with live data to make smarter buys. In 2026, the leanest resellers are the ones who thrive, and our portal is built to be the leanest tool in your arsenal. Check out our eBay fee calculator to see exactly how we help you keep more of what you earn.

Resilient Research & Manual Fallbacks

Not everything worth flipping has a barcode. Whether it's a vintage collectible or a unique piece of houseware, our tool adapts. Our manual search portal allows you to type in keywords or model numbers to get the same rapid-fire marketplace comparisons. It's the same Point, Shoot, Go mentality, even when using the keyboard. This ensures that you can tackle specialized niches where others are limited by their scanner's internal database.

By using Thrifty Flipper, you're joining a community of smart, efficient resellers who prioritize their bottom line. We've kept the experience ad-supported to stay free forever, allowing you to reinvest your savings back into your inventory. Share this tool with your fellow flippers and let's make 2026 the year of the agile, independent reseller. No subscriptions, no fluff—just pure sourcing speed at your fingertips.

Remember, the back button is your best friend. Scan, check, back, repeat. It's the rhythm of profit.
