1. Sign up for autopay. You get a $5 discount each line. I just realized this only with in this past year. We've had Sprint for like the past decade and could have saved a bunch
2. AAA has a promotion going until 1/12 (I think). If you go to sprint.com/aaapaid and enter your membership# they'll pay your membership for Classic or Basic and you get a monthly discount. $15 off my bill starting this month, though I think it depends on your plan. We have the unlimited one for 3 lines.
