Scan any retail product's barcode and instantly see if it's a profitable resell on Amazon, eBay, Poshmark, and Facebook Marketplace. Camera scan → profit calculation in real-time. Built for resellers, flipsters, and side-hustlers. $14.99/month.
Retail Arbitrage Scanner is a mobile-first app that lets resellers instantly check if a product they're looking at in a store is worth buying for resale. Scan the barcode with your phone camera, get instant analysis: current Amazon/eBay/Poshmark/Facebook Marketplace prices, historical price trends, fees calculated (Amazon FBA fees, eBay fees, shipping costs), and actual profit estimate after all costs. Green = buy it. Red = pass. One scan eliminates the guesswork and research time that slows down every reseller's shopping trips.
Resellers make faster, smarter purchasing decisions. Average profit per item goes up because they're not buying stuff that won't resell. Time spent in stores is more efficient. Beginners avoid the costly mistake of buying products they can't sell for profit.
Point your phone at any retail product barcode. Camera scan using device ML (Apple/Google ML Kit). Instantly recognizes UPC, EAN, ISBN codes. No manual entry needed. Scan works in any lighting condition. Supports: UPC-A, UPC-E, EAN-8, EAN-13, ISBN-10/13.
After scan: display current prices across Amazon (FBA + FBM), eBay (sold listings for accuracy), Poshmark, Facebook Marketplace. Shows: lowest FBA price, lowest FBM price, average selling price, number of sellers, 30/90-day price trend. Historical chart shows if price is trending up or down.
Input your buy price. Calculator computes: selling price minus marketplace fee (varies by category), minus FBA fulfillment fee (or shipping cost for FBM), minus storage fees (for seasonal items), minus other costs (labels, bubble wrap, etc.), equals actual net profit. Shows ROI % and annualized return. Color-coded: green (>$5 profit, >30% ROI), yellow ($2–5), red (<$2 or negative).
Last 100 scans stored locally. Can build a shopping list in-app: scan products, save the ones you want to buy, at end of trip review your list with estimated total profit. Useful for thrift store runs where you scan 20 things and buy 5.
Premium: save products to watch list. Get notified when Amazon price drops below your threshold. Useful for "I saw this at $20, it's usually $30, should I wait for a price drop?" Alert at your target buy price.
Not just a scanner — built-in tips explain how to read the data. "Why is the Amazon price higher than retail? Because FBA fees make it unprofitable for most sellers." Contextual education for beginners embedded in the scan results.
Track your scanning history over time. See: what categories you're best at finding deals in, average ROI, total profit estimated, most profitable stores. Helps resellers understand their sourcing patterns and improve.
Uses public clearance patterns: certain stores markdown on specific days (Target markdown Wednesdays, for example). Alerts you when you're near a store with recent markdown activity on items that tend to have high resale value.

| Metric | Why It Matters |
|---|---|
| Scan Frequency | Active users scan daily. Inactive users don't come back. Track 7-day and 30-day return rates. |
| Buy Rate | Of scanned products, what % do users actually buy? High buy rate = high confidence in profit estimates. |
| Profit Accuracy | Do actual sale prices match estimates? Track via user-reported sale data. Confidence in numbers = trust in product. |
| Time-to-decision | Users should be able to scan and decide in under 10 seconds. Speed is a key feature. |
| Risk | Mitigation |
|---|---|
| Price data goes stale | Real-time API calls when scanning. Cache for 5 minutes to avoid rate limits but never serve stale data. |
| Amazon API rate limits | Use Product Advertising API for pricing. If rate limited, show last-known price with staleness warning. |
| Competitors with more data | Focus on the reseller community and education layer. Price is secondary to trust and accuracy. |
| FBA fee miscalculations | Use Amazon's official fee calculator API. Update immediately when Amazon changes fee structure. |
