The longer the term, the less you pay per month
What you see is the MozOut list price, the same today and on renewal. This plan has no promotional price.
It renews at the same price you pay today, on the same cycle, automatically. You can see or change this in your Client Portal.
* Plans are pre-paid: you pay the full amount at the time of purchase. For comparison, the monthly equivalent is the full price spread over the number of months contracted.
