# Regional Resale Watchlist

Monitor used inventory across regions by checking marketplace coverage, searching listings, comparing retail context, and saving watchlist snapshots.

Used-goods sourcing works best when you know which marketplaces actually matter in a region and how the resale market compares with broader retail pricing. Without that context, teams either over-monitor weak sources or assume a used listing is attractive when it is barely cheaper than buying new.

This workflow creates a tighter operating loop. Start by checking source coverage, run the actual resale search, compare the market against retail context, and finish with a compact watchlist that can be rerun as inventory changes.

**Tools:** marketplace-search, web-search
**Category:** search

## Steps

### 1. Check source coverage

Confirm which marketplaces are actually available for the target regions and listing classes before you spend time refining the search.

- **Tool:** marketplace-search
- **Skill:** source_coverage
- **Input:** Target regions, listing classes, and optional source preferences
- **Output:** Coverage rows showing active marketplaces, caveats, and region support

### 2. Search marketplace inventory

Run the regional listing search across supported sources to find current used inventory, local-pickup options, and source-specific supply.

- **Tool:** marketplace-search
- **Skill:** search_listings
- **Input:** Product query with condition, region, source, and pickup or delivery filters
- **Output:** Deduped listing cards with source names, URLs, snippets, and price text

### 3. Compare against retail context

Search broader shopping results to understand whether the resale market is genuinely attractive versus new-product pricing.

- **Tool:** web-search
- **Skill:** shopping_search
- **Input:** Product or model search query for retail comparison
- **Output:** Shopping results with merchants, price signals, and product context for baseline comparison

### 4. Save the watchlist snapshot

Produce a compact watchlist output that captures the listings worth monitoring and can be rerun on a schedule later.

- **Tool:** marketplace-search
- **Skill:** watchlist_snapshot
- **Input:** The final marketplace query and filters that define the recurring search
- **Output:** Compact snapshot rows with stable IDs, listing URLs, and source context for follow-up

## Benefits

- Prevents wasted effort on regions or marketplace types with weak coverage
- Combines resale discovery with a simple new-versus-used pricing check
- Produces compact watchlist rows that are easy to rerun later
- Helps sourcing teams separate strong leads from search noise quickly
