About Our Data & Methodology
Drop Beacon aggregates publicly listed prices for everyday-carry (EDC) gear and normalizes them across retailers. Prices shown on product pages are live — refreshed continuously by our scrapers — and are the authoritative source. We link out to the retailers that sell each product and are monetized via affiliate click-through.
Where the data comes from
We monitor maker and retailer storefronts directly — Shopify, WooCommerce, BigCommerce and other platforms — refreshing high-priority brands roughly every 30 minutes. When the same product is sold by multiple retailers, we match it to a single listing and show every price side by side. Secondary-market data comes from Reddit buy/sell/trade (BST) communities, eBay sold listings, and reseller stores.
How fresh prices are
Product-page prices are computed from the most recent scrape, and price-drop detection runs continuously. Freshness is the whole point of an aggregator, so we treat it as the authoritative signal — and we never present a stale price as current. A price can still change between our scrape and your click, so always confirm the final price at the retailer.
Our derived metrics
Beyond raw prices, Drop Beacon computes synthesis you can't get from a single storefront: sell-through velocity (share of tracked drops that have sold, gated to ≥3 verified sales), median time-to-sell, and resale premium (secondary-market price vs retail). These come from our own observation history — what we've watched actually happen across 109,303 products over time.
Honesty & limitations
We aggregate public data and link out; we don't sell products or hold inventory. Specifications are best-effort and occasionally extracted automatically. Some retailer links are affiliate links and we may earn a commission at no cost to you — this never affects which prices we display. If we publish a dataset anywhere else, treat it as a dated, point-in-time snapshot, not current pricing.
Frequently asked
Where does Drop Beacon get its prices?
Directly from maker and retailer storefronts (Shopify, WooCommerce, BigCommerce and others), scraped on a schedule — high-priority brands roughly every 30 minutes. Drop Beacon currently tracks 1,179 EDC brands and 109,303 products across about 26 retailers.
How fresh is the pricing?
Prices shown on product pages are live — computed from the most recent scrape — and are the authoritative source. Price-drop detection runs continuously. We never publish a stale price as current; any exported dataset snapshot is point-in-time and should not be quoted as the current price.
What do 'sell-through' and 'resale premium' mean?
Sell-through is the share of a brand's tracked drops that have sold, gated to at least 3 verified sales so we never report '100% sold' off normal retailer-feed churn. Resale premium is the secondary-market price relative to retail (a positive premium means it trades above MSRP). Both are derived from Drop Beacon's own observation history, not restated from a third party.
Where does the secondary-market data come from?
From Reddit buy/sell/trade (BST) communities, eBay sold listings, and reseller stores — 23,507 listings tracked. We surface average resale price, whether an item trades at a premium or discount to retail, and how liquid the market is.
Does Drop Beacon sell products?
No. Drop Beacon aggregates publicly listed prices and links out to the retailers that sell the product. We're monetized via affiliate click-through, which never changes which prices we show — we list the live price from every retailer carrying a product.
Can I trust an exported dataset snapshot as current pricing?
No. Only the live product pages on edc4me.com are authoritative. Any dataset published elsewhere is a point-in-time snapshot and may be outdated.
