If you're doing retail arbitrage or online arbitrage on Amazon or Walmart, you need a scanner. ScanUnlimited is popular. It's fast and cheap. But is it the right tool for your business? The answer depends on what you're selling, where you're selling, and whether you want to stay in one tool or integrate sourcing with inventory management, repricing, and order management.

Switch to Ecom CirclesWhy Sellers Switch to Ecom Circles
Walmart Support (Game Changer)
ScanUnlimited doesn't support Walmart. Ecom Circles scans Walmart natively. One tool for two major channels.
IP Protection
Ecom Circles flags restricted brands BEFORE you buy. Saves thousands on avoided suspension risks.
All-in-One Ecosystem
Scan, calculate profit, track inventory, set repricing. All in one platform. Less tool switching.
Real Profit Math
Ecom Circles calculates true profit: product cost + fees + your target margin. ScanUnlimited is often wrong.
Bulk Sourcing Power
Upload 20K items from suppliers. Instant profitability data. ScanUnlimited can't do this at scale.
No More Tool Juggling
One platform instead of ScanUnlimited + repricer + inventory manager. Lower total cost.
Which Platform for Your Business?
Solo RA Seller (Amazon Only)
ScanUnlimited works IF you're okay with basic profit math. Switch to Ecom Circles within 3-6 months when you want Walmart or scale.
OA Seller (Amazon + Walmart)
Use Ecom Circles. ScanUnlimited won't scan Walmart. You'd need a second tool anyway.
Wholesale Sourcing (10K+)
Ecom Circles only. Designed for wholesale. Upload 10K items, filter by profit. ScanUnlimited can't.
Dropshipping (Shopify + Amazon + Walmart)
Ecom Circles. Multi-channel, integrates with Shopify. ScanUnlimited is Amazon-only.
Testing (Lowest Budget)
ScanUnlimited is cheapest. But plan to switch. Ecom Circles grows with you; less switching pain later.
Beyond Scanning: The Full Sourcing Toolkit
Ecom Circles is more than a scanner. Once you've found profitable items, track your inventory across all channels in real time, ensuring you never oversell. Know exactly how much stock you have at each warehouse and when you need to reorder.
Then, keep your prices competitive. Automated repricing rules adjust your prices based on competition, inventory levels, and margin targets. Scan items, load them into inventory, and let repricing maximize your profits. No more manual updates across Amazon and Walmart.

Loved by eCommerce Sellers Worldwide
See how real sellers source faster and scale with Ecom Circles.
I needed a repricer that covered my different selling methods. Using the Ecom Circles Repricer made us significantly more competitive on both Walmart and Amazon.
There's no way we could have brought in almost $45k in profit over Black Friday / Cyber Monday weekend without it.
It's the best software I've used. It makes it easy to scale while making sure nothing falls through the cracks.
