Why Sold Comparisons Are the Best Starting Point

For resellers, pricing can feel mysterious—but it doesn’t have to be. The most reliable way to set a price is to look at what similar items have actually sold for recently. This simple method helps you avoid overpricing (leading to unsold inventory) or underpricing (leaving money on the table). Here’s how to make this approach work for you, even if you’re just starting out.

Step 1: Identify the Exact Item

Begin by gathering all the details about your item—brand, model, size, color, condition, and any unique features or flaws. The more specific you are, the more accurate your pricing will be. For example: “Nike Air Max 270, men’s size 10, black/white, gently used, original box included.”

Step 2: Search Sold Listings on Major Platforms

  • eBay: Search your item, then filter results to "Sold Items". This shows real prices buyers paid, not just asking prices.

  • Mercari, Poshmark, Facebook Marketplace: Use their search features and look for sold or completed sales.

Look at multiple platforms if possible. Some niches perform better on specific sites.

Step 3: Compare Apples to Apples

Scroll through sold listings that match your item’s condition and details. Make note of:

  • Condition (new, used, refurbished)

  • Included accessories or packaging

  • Color/variant differences

  • Recent sale dates (focus on last 30–90 days)

Write down the sale prices of 4–10 closely matching items. Avoid outliers (like damaged items or bulk lots).

Step 4: Set a Realistic Price Range

Calculate the average of your comparable sales. If your item is in especially good or bad condition, adjust the price up or down accordingly. Consider:

  • High end of the range for new, pristine, or rare items

  • Low end for used, incomplete, or common items

Don’t forget to factor in selling platform fees and shipping costs when you calculate your net profit.

Step 5: Use a Central System to Stay Organized

To avoid confusion and double-selling, it’s important to keep your inventory and listings in sync across all sites. A simple spreadsheet can work when starting, but dedicated tools save time as you grow. Platforms like Gavelbase let you:

  • Track inventory across multiple marketplaces

  • Sync listings to prevent double-selling

  • Assign team roles (e.g., listing, shipping, support)

  • Track sales, fees, and net profit

  • Handle shipping or local pickup cleanly

If you’re working with a team—even family or friends—assign basic roles so everyone knows their tasks (e.g., who handles photos, who ships, who replies to questions).

Step 6: Monitor and Adjust

Pricing isn’t set-and-forget. If your item hasn’t sold after a couple of weeks, check if recent sold prices have shifted. Consider small price drops or adjusting your listing (better photos, clearer descriptions). If you get lots of interest but no buyers, your price may be just slightly high—or your shipping cost might be a barrier.

Step 7: Handle Shipping or Pickup Smoothly

When an item sells, act quickly:

  • Mark the item as sold in your inventory system

  • Prepare for shipping or coordinate local pickup

  • Update your records for fees, shipping costs, and profit

Clear communication and fast shipping or pickup earn better reviews and repeat buyers.

Beginner-Friendly Tips

  • Start simple: Even a notebook or Google Sheet is fine for your first few items.

  • Be honest: Accurate descriptions and photos mean happier buyers and fewer returns.

  • Check fees: Every platform has its own fee structure—factor this into your price.

  • Watch shipping: Use calculated shipping or flat rates based on real costs so you don’t lose money.
