Best online arbitrage tools for Amazon sellers, priced and compared

Best online arbitrage tools by step

The best online arbitrage tools work in three steps: Tactical Arbitrage finds deals by scanning retail stores, SellerAmp SAS checks each find for profit, and Keepa shows the price history behind it. Tactical Arbitrage is sold inside Threecolts Seller 365, where Standard is $69 a month on Monthly. SellerAmp SAS Getting Started is $19.95 a month. Prices are as read on October 29, 2026.

Among online arbitrage sourcing tools, SmartScout covers a different start: a supplier price list instead of a store page. Basic is $49 a month on the Monthly view, or $29 a month on the Yearly view, paid as $348 for the year at checkout. Amazon defines retail arbitrage as buying from retail stores at lower prices and reselling, and tells sellers to calculate margins first.

Online arbitrage tools with trials and prices

Tactical Arbitrage's site offers a 7-day trial while the Threecolts Seller 365 page it sends you to offers 14 days, 7 at once and 7 more after you connect an Amazon or Walmart seller account. AMZScout sells prepaid terms, not monthly billing, and labels a 10-day money-back guarantee.

Threecolts does not say whether its Annual option is billed once a year, and its plan cards and comparison table give different scan limits, so this page states no per-plan limit.

Store scanning against price list scanning

Tactical Arbitrage says it searches 1,400+ stores and their categories, analyzes an uploaded wholesale manifest and runs Reverse Search from an Amazon listing back to source stores. SellerAmp SAS adds Storefront Search, which shows its analysis for the products in any seller's storefront, and lists the other offers on a product with seller name, rating, review count and fulfillment type. Its sales a month are SellerAmp's estimates.

SmartScout's online arbitrage page says it starts on Amazon's side and does not generate product lists. Its UPC Scanner takes a CSV or Excel list of UPCs from any supplier; ASINs and EANs also work. Revenue figures it returns are modeled estimates. Caps run from 5,000 ASINs on Basic to 200,000 on Enterprise, per the plan grid.

Amazon adds that drop-shipping retail-to-retail is prohibited and that auctions and liquidation are not valid sources of supply. See SmartScout vs Tactical Arbitrage.
