How this site works
No scraped listicles and no guessed numbers. Each model's price is copied from the provider's own pricing page, the source URL is stored next to the price in our data file, and the date we last checked is printed on the page. When a provider changes a price, we update the data file and every page on the site is regenerated from it.
