It means you pay in full, but if you take a look at the total price of 83.xx it equals 6.95/month (if it was paid monthly). Basically, you just save 12 dollars if you prepay for a full year.
12 x 7.95 = 95.40
12 x 6.95 = 83.40
But to get the discount, the whole year is paid for up front. That's all
Just a way to break it down so people see the discount for prepaying a year.
Hope that helps!
