Frequently asked questions

What does the percentage in the basket measure?

The gap is (used original − new reissue) for items with both references; percentage divides it by the used total of that same matched subset. Missing used prices mean a partial comparison, not a whole-basket discount. No missing value becomes zero.

Why are originals missing? Some releases have no documented home AES equivalent, others have unreliable resale data, particularly in EU and JP. We do not substitute MVS conversions, reproduction carts or suspicious listings. A shared link contains your selected IDs and region; the browser saves your selection locally.
