Prepaid Riot Cards?

When you redeem it does it automatically purchase the RP or does it add balance to your account? Like if I pick up a 25$ RP card will I be able to just use 20 dollars and save up for another 25$ and buy the 35$ package on my next RP card purchase in the future?
Thank you to all those who serve our country :)
