Daily prices and in-stock state across consumer electronics categories on the largest Dutch-language retailer.

Collection begins 2026-09-19; the schedule is not live yet.
Daily, once scheduled · Six categories, several hundred products a day

Why this cannot be bought later

A retailer shows one price and one stock state: today's. How often something sells out, how long a discount runs and whether a price rose before it fell are all invisible without a daily record.

What the series holds

CategoriesCoffee machines, laptops, headphones, vacuums, monitors and printers on bol.com.
Per productPrice, list price, availability, rating and review count, keyed on product id and EAN.
DerivedPrice changes, discount depth, how often a product goes out of stock and how long it takes to return.

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.
