ION channel 250 is in the 120 line up. ION is also an OTA local channel in many areas. In the Tampa area, it is channel 66-1 with sub channels 2-3-4-5-6
Channels are arranged contractually by the channel owners. Also, as far as how much you pay for AT120, it does not have a large profit margin to add additional channels. The majority of what you pay now goes to the channel owners for the channels included in your package. To add more, would be to add more to the cost. Yes, they must still also make a profit(even a slim one like currently) and are not in the business of charity. They still offer frequent free previews if you do not want to add a package that includes the Hallmark channels, such as the Heartland pack for $6.
