I can't find any clear information about the terms considering the subscription service for the standard version of Parallels. It's listed as $6.66 per month, but when I go to purchase it, it's listed as $79.99. Does this mean I pay $79.99 off the bat, or is that the cumulative cost of the program over the course of one year and I pay $6.66 once I put my card in? I feel slightly mislead by the initial lack of clarity on this. Thanks.
