Each offering on the pricing page links to its own page of plans, read at its latest capture.
How the plans got here
Plans, prices and descriptions are quoted from the vendor's own pricing page as we read it on each date. A plan missing from a later reading is shown as no longer listed on the page — a statement about the page, not the product. Readings that failed to show any plans are left out rather than read as a change.
