eBay sold comps Chrome extension: check market price without opening sold listings

Sold comps are the reseller truth serum. Asking price is what the seller wants. Sold price is what the market already accepted.

The problem is speed. If you check sold listings manually, every sourcing session turns into a pile of tabs: active listing, sold filter, similar listing, calculator, fee estimate, shipping estimate. You lose the deal while doing the homework.

An eBay sold comps Chrome extension solves that by putting the market check directly on the page you are already browsing.

What the extension should show

A useful sold-comps overlay should do more than say “cheap” or “expensive.” At minimum, it should show:

• The current listing price.
• A recent sold-comp median or range.
• A buyer verdict like Great, Good, Fair, High, or Overpriced.
• A reseller verdict that includes estimated fees and profit.
• The comps behind the verdict so you can audit the math.

My Deal Verifier shows buyer and reseller verdicts on eBay search result tiles and item pages. The point is not to replace judgment. The point is to remove the repetitive math so you can spend your judgment on condition, variants, seller quality, and timing.

Why search-result badges matter

Most tools make you open a listing first. That is too late when you are scanning a full eBay search page.

Per-tile badges are faster because they let you triage the page:

• Green means worth opening.
• Neutral means maybe, depending on condition.
• Red means skip unless something special is hiding in the listing.

This is especially useful for categories with lots of near-duplicates, like G-Shocks, Seiko watches, Pokemon boxes, camera lenses, game consoles, vintage electronics, and parts lots.

What can make a sold-comp score wrong

Automated comps need guardrails. Be careful when:

• The listing title is vague or keyword-stuffed.
• The model has many variants.
• Condition drives most of the value.
• The item includes accessories, boxes, papers, manuals, or missing parts.
• Recent sales are too sparse to make a confident median.

That is why the best overlays expose the comps instead of hiding them. If the score says Great but the comps are for a different model, you should be able to see that before buying.

Buyer mode vs reseller mode

Buyer mode asks: “Am I paying less than recent market value?”

Reseller mode asks: “Can I resell this after fees, shipping, and risk?”

Those are different questions. A listing can be a good personal buy but a bad flip. If a $120 item usually sells for $145, that may be a fine buyer deal. After eBay fees and shipping, it probably is not enough margin for resale.

My Deal Verifier separates those verdicts so shoppers and resellers do not have to use the same threshold.

The fastest workflow

Open an eBay search, let the extension scan the visible tiles, open only the listings with good verdicts, then inspect the comps and condition before buying. If you source from Japan too, check whether the same item appears on Buyee at a lower landed cost before paying the eBay markup.

That workflow keeps you fast without making you blind.
