Daily, 05:10 UTC · ~1,444 products a day across six categories
The caseWhy this cannot be bought later
A retailer shows one price and one stock state: today's. How often something sells out, how long it stays gone, and whether a price rose before it fell are all invisible without a daily record.
ContentsWhat the series holds
| Categories | Coffee machines, laptops, headphones, vacuums, monitors and printers on bol.com. |
| Per product | Price, availability, rating and review count, and whether the price is bol's own or a marketplace seller's. Keyed on product id. |
| Derived | Price changes, how often a product goes out of stock, and how long it takes to return. Not discount depth: bol publishes no list price on its search pages, so there is nothing to measure a discount against. |

What it cannot tell you
Availability is read from the retailer's own delivery wording. A phrase matching neither in-stock nor out-of-stock is recorded as unknown rather than guessed, because a wrong in-stock reading is worse than a missing one.
