Every experienced reseller knows the drill: find an item, search eBay's sold listings to check prices, note the data, then repeat the process the next time you find a similar item. This constant re-searching of sold comps wastes hours every week. Here's how to build a pricing database that saves you time and helps you make faster sourcing decisions.
The Problem with Re-Searching
How many times have you searched "TI-84 Plus Calculator sold listings" on eBay? If you sell the same types of items regularly, you're probably re-searching the same products dozens of times a year.
Each search takes 2-3 minutes. At 10 comp searches per sourcing trip, that's 20-30 minutes of pure research time.
Building a Comp Database
The Simple Spreadsheet Method
Create a Google Sheet or Excel file with these columns:
- Product Name — What the item is
- Category — Your sourcing category
- Low Price — Lowest recent sold price
- Average Price — Average sold price
- High Price — Highest recent sold price
- Condition Notes — Typical condition descriptions
- Max Buy Price — Most you'd pay to maintain good margins
- Last Updated — When you last checked comps
- Notes — Anything else useful
How to Use It
When you're out sourcing, find an item that looks promising, check your spreadsheet first (takes 10 seconds). If it's in your database, you already know the buy price threshold. If it's not, search comps normally, then add it to your database.
When to Update
- High-volume items: Update monthly
- Seasonal items: Update before and after their peak season
- Stable items: Update quarterly
- Trending items: Update weekly
Advanced Comp Strategies
Track Price Trends
Don't just record a single price — track the trend. Is the item's value going up, down, or stable? Are there seasonal patterns? Has eBay recently changed fee structures?
Condition-Based Pricing Tiers
For items where condition significantly affects price, track separate tiers:
- Mint/New: Price range
- Good/Used: Price range
- Fair/Acceptable: Price range
- For Parts: Price range
Category Benchmarks
Establish minimum margin thresholds by category:
- Electronics: 3x minimum (buy at $10, sell at $30+)
- Clothing: 5x minimum (buy at $5, sell at $25+)
- Books: 10x minimum (buy at $1, sell at $10+)
- Video Games: 4x minimum (buy at $5, sell at $20+)
These benchmarks help you make instant buy/pass decisions.
