Price watch

Where a vendor publishes prices, the figures on this site come from that vendor's own pricing page, read on the date shown; in two comparisons one figure comes instead from the vendor's own article, and that source is labelled as such on the page; where a side has no published price, the page says so and the figure is an editable estimate (the Status column below shows which is which). A script re-reads the official pages every day and a person re-reads the ones a script cannot every week. When a vendor changes a price, the change is reviewed and listed here before the calculator is updated.
