CGL - Why am I getting a message that the price is the same for up to a number of hours?

Occasionally the price for, say, 2 hours of coverage is the same as the price for 1 hour of coverage (e.g. $5.00). If this happens, the system will let you know with a banner that displays the maximum number of hours you may purchase at the same price. You may then select the greater number of hours, if required.
