ONE FIELD, and it carries the billing commitment when the figure requires one: "from $2,417/month billed annually" is a yearly contract divided by twelve, not a month-to-month rate. Where the row holds a real month-to-month price that is what the figure is, and no term is stated. Do not parse the amount out of this string expecting a monthly rate.'
