Frequently Asked Questions & Facts
Everything you need to know about how Markdown Signal tracks and verifies deals.
Q: What is Markdown Signal?
Markdown Signal is a real-time autonomous intelligence radar that discovers retail clearance drops, open-box misprices, and high-margin warehouse liquidation items across Amazon, Best Buy, Walmart, and eBay.
Q: Is Markdown Signal really 100% free?
Yes. All deal browsing, filtering, and restock tracking are completely free without paywalls or subscriptions. Markdown Signal is funded through affiliate referral links with supported retailers at zero extra cost to you.
Q: How is the Opportunity Score calculated?
Our proprietary scoring algorithm evaluates four deterministic pillars: depth of discount against baseline market value, profit margin after simulated marketplace fees, historical price stability floor, and cosmetic condition rating.
Q: Do I need an account to browse deals?
No. You can search, browse, and click out to retailer deals without creating an account. An account is only needed if you want to sync your saved watchlist across devices or set up automated notifications.
Q: How fast are warehouse restock deals updated?
Our background Celery workers run continuous discovery cycles every few minutes across all supported retailers. Because open-box items and pricing glitches can sell out in minutes, our live radar refreshes dynamically.
Q: How does Sign in with Google work?
We use Google's official OAuth 2.0 OpenID Connect. We only request your name and email to identify your account and set up your session. We never access your contacts or private Google files.
