Find underpriced eBay items by proving the exact product, condition and resale market.

Underpriced means below a defensible market level

The reference point must come from relevant versions of the same product, not a broad category average.

Verify the exact variant

Storage, colour, edition, size, generation and bundle contents often explain what first looks like a pricing mistake.

Normalise condition

A pristine tested item and an untested damaged item are not interchangeable comparables.

Remove obvious outliers

One unusually high asking price should not become your resale estimate. Look for a cluster of relevant evidence.

Leave headroom for uncertainty

If evidence is sparse, reduce the amount you are willing to pay rather than increasing confidence to make the deal look better.
