Kraków, PL · prices in PLN · ships to 24 countries. Catalogue read from c4c.shop's own public product feed on 2026-10-13. Every figure below is an observation from that feed, not an estimate.
Sales estimate
Derived from stock levels falling between polls, over 3 observed days. Intervals where stock rose, or where a variant sat at the store's inventory ceiling, are discarded rather than counted as zero sales.
| Date | Units sold | Est. revenue | Method | Catalogue read | Discarded |
|---|---|---|---|---|---|
| 2026-09-14 | 0 | not measurable | index only | — | 00 |
| 2026-09-04 | 0 | not measurable | index only | — | 00 |
| 2026-08-12 | 0 | not measurable | index only | — | 00 |
An estimate, and the page shows what it rests on: which method produced each day, how much of the catalogue could be read, and how many intervals were thrown away. A day marked not measurable is not a day without sales — it is a day we could not defend a number for.
