BuyHub
The ultimate shopping app for collectors: 100+ marketplaces in a single search box, track prices with Radar and buy directly on every store.
Core Capabilities
BuyHub centralizes collector-focused shopping functionality across a global network of marketplaces to eliminate the need to browse multiple individual platforms separately.
Single-box cross-marketplace search that pulls results from over 100 marketplaces spanning 129 countries, with no need to navigate to each individual store site to run queries.
Radar price and listing tracking that sends real-time alerts the moment a matching item becomes available, giving users an early advantage over other potential buyers.
In-app purchase workflow that lets users sign into their existing accounts for each supported store and complete transactions directly on the original store platform, without navigating away from the BuyHub interface.
Multi-term search that processes multiple distinct search queries at once, merges all returned results, and automatically removes duplicate listings to streamline browsing.
Saved search functionality that preserves custom configured searches with all applied advanced filters, so users can view newly added matching items at a glance without reconfiguring parameters.
Automatic currency conversion that displays all listing prices in the user's selected local currency, and automatic title translation that converts all listing descriptions to the user's preferred language.
Exclusive advanced search filters that are not available on most individual marketplaces, including controls for seller country, listing recency, price range, item condition, and custom inclusion or exclusion of specific keywords from results.
Mobile app support that extends all core desktop features to portable devices, with real-time push notifications for Radar alerts.
Multi-account linking for supported store platforms, allowing users to associate multiple separate accounts for the same marketplace and switch between them as needed.
Custom auction alerts that notify users of upcoming auction end times, with configurable notification timing and optional price cap thresholds to suppress alerts if an item's bid exceeds a set value.
Supported Workflows
BuyHub is structured to support three sequential, low-friction steps for collector shopping:
Search: Enter a target item or multiple related search terms, and select which of the 100+ supported marketplaces to query. The app runs all selected searches simultaneously across the chosen platforms.
Compare: View aggregated, deduplicated results from all queried marketplaces in a single interface, then apply advanced filters to narrow listings by price, condition, seller location, listing age, and keyword rules to isolate exact matches.
Buy: Access the original store's checkout flow directly within BuyHub by signing into the user's existing store account, with no additional redirects or third-party checkout steps. No buyer commission is applied to any completed purchase.
Users can also set up persistent tracking workflows by saving filtered searches and enabling Radar or auction alerts, so they receive immediate notifications when new matching items are listed or when followed auctions are nearing their end, without needing to manually re-run searches on a regular basis.
Target Audience
BuyHub is built exclusively for serious collectors who regularly source hard-to-find items across multiple regional platforms. It is designed to support collectors shopping for a wide range of niche categories including retro collectibles, Pokémon, watches, vintage clothing, sneakers, Lego, and action figures. The toolset addresses the specific pain points of collectors who previously had to manually check dozens of separate marketplace sites across different countries, languages, and currencies to locate rare or underpriced items.
Plan Details and Pricing
BuyHub operates on a freemium model, with no buyer commission charged on any purchases made through the platform. A free account tier is available, and uses the same login credentials as Museum.app for seamless cross-service access.
Additional advanced features including the ability to link multiple accounts per store, and auction alerts delivered via app, browser, and email, are reserved for the Pro and Max paid plan tiers.
Current Limitations
No explicit usage limitations are documented for the core free and paid feature sets. All listing data and transaction processing remains tied to the original host marketplace, so users are still subject to the individual terms of service, shipping policies, and return rules of the store where each item is listed.
