Corrections are the most useful thing you can send. If a figure here does not match what the vendor publishes today, tell us and we will re-check the page and re-date the entry.

Adding a vendor

We add vendors that publish enough pricing detail to compute a monthly total, and we list ones that do not publish prices as quote-only. Send a link to the pricing page. We do not accept payment for inclusion or position — see Method.

Before you write

If the question is what a vendor costs, the calculator may already answer it, and the vendor list shows which vendors publish nothing at all.
