Market Price Research

Overview

This skill enables research of fair market prices for second-hand items in Melbourne, Australia by analyzing recent sold listings on eBay.com.au. Provides price ranges, typical selling prices, and market insights based on actual completed sales.

When to Use This Skill

Use this skill when users request:

  • "What's the fair price for [item]?"
  • "How much is my [item] worth?"
  • "What do [items] sell for in Melbourne?"
  • "Research prices for [item]"
  • Any query about second-hand item valuation in Melbourne

Research Workflow

1. Understand the Item

Gather specific details about the item:

  • Brand and model (exact model numbers if available)
  • Condition (new, like new, good, fair, poor)
  • Age or year of manufacture
  • Any notable features or accessories
  • Any defects or missing components

2. Search eBay.com.au Sold Listings

Construct searches using the eBay Australia sold listings filter. See references/ebay_search_guide.md for detailed search URL construction patterns.

Key search parameters:

  • Use specific brand/model terms
  • Include condition keywords when relevant
  • Filter to "Sold items" to see actual sale prices (not just asking prices)
  • Consider location filtering to Melbourne/Victoria for local market insights
  • Look at listings from the past 30-90 days for current market trends

3. Analyze Price Data

Review 10-20 recent sold listings to identify:

  • Price range (lowest to highest)
  • Median/typical selling price
  • Outliers (unusually high or low, with reasons)
  • Condition correlation (how condition affects price)
  • Seasonal trends if applicable
  • Shipping vs pickup prices

4. Provide Market Price Assessment

Present findings in a clear format:

  • Fair Market Price Range: Based on typical sales
  • Condition Impact: How condition affects pricing
  • Recent Sales Data: Number of items analyzed, date range
  • Market Observations: Any notable trends or factors
  • Recommended Pricing: For selling or buying
