............per year/per one more year.......... 1. A one-year subscription package for my smartphone network is $400 per year. 1. A two-year subscription package for my smartphone network is $300 per year. 1. A three-year subscription package for my smartphone network is $250 per year. 2. The package is cheaper on a per year basis. 3. The package is cheaper per one more year of subscription. 4. The packages are cheaper per one more year of subscription. I just made up the rate for my network expense. I tried to talk about this. How do #2/#3/#4 sound? Do they sound natural? How would you express that? Thank you and good morning. :)
