# Price Ledger

> We track game prices, PC hardware and exchange rates daily and write only when something actually moves. Every number comes from our own observation log.

## What we measured

We measure prices and exchange rates on a fixed schedule and keep them as time series. Every number in every post comes from that log, and each post shows how many times and when we measured. The raw observations behind each post are also published as machine-readable JSON.

When citing, please include the observation time. A price without a timestamp is meaningless, and expired deals are marked as ended on the page.
