How these best sellers are chosen
How is this ranking built?
The order is what people actually bought over the last 12 months: every purchase made through the site counts, on a rolling window that drops sales older than a year, so the ranking keeps up with the market instead of freezing all-time totals.
How often does it change?
It is rebuilt with every update of the site, and the 12-month window moves with it, so a product that starts selling more climbs the list on its own and one that stops selling drops out. The date at the top of the page is when its prices were last checked.
Where do the prices come from?
Prices, discounts and ratings are refreshed continuously, so every card shows live pricing and the latest customer feedback.
