Arbitrage & Sourcing tools

• Item-by-item checks. SellerAmp SAS is a browser extension plus a mobile app for in-store scanning, with profit and eligibility checks on any page. Plans run $19.95, $29.95 and $49.95 a month. Seller Assistant covers similar ground and adds IP-complaint alerts and a bulk restriction checker; its entry Pro plan costs $29.99/mo, or $24.99/mo billed annually, with two seats.
• Online arbitrage at volume. Tactical Arbitrage scans more than 1,000 retail sites across seven countries and also handles wholesale lists and book flips. It is now sold only inside Threecolts’ Seller 365 bundle, from $69/mo.
• Wholesale price lists. Scan Unlimited turns distributor CSVs into sourcing lists. A free plan allows one upload a month of up to 10,000 products; the Unlimited plan is $70/mo, or $60/mo billed annually.

A profit figure is only as good as the fee and velocity data underneath it. Look for a full FBA fee calculation, price and sales-rank history rather than a single snapshot, and an eligibility check run against the seller’s own account, because a profitable item that cannot be listed is worth nothing. SellerAmp integrates with Keepa but needs a separate Keepa subscription for full value, so budget for both. For brands with a record of IP complaints, an alert before purchase is cheaper than a listing suspension afterwards.

BQool appears here because it is a budget repricer popular with arbitrage sellers: from $25/mo, with the Basic plan covering 50 AI-repriced listings plus 1,000 rule-based ones, on Amazon only. The usual errors are buying Tactical Arbitrage’s breadth for a part-time operation, paying for both SellerAmp and Seller Assistant when they overlap heavily, and judging demand from one day’s sales rank.
