@Sydthekid The best code is a friend referral code for your sister 🙂 I assume you are PM subscriber already, make sure you give her your friend referral code. She will get to save $10 and you will save $1 or 1 Public point for every cycle she is on
For promotion code, it usually comes once a month. i would assume with summer or back to school coming, there should be some kind of bonus data promotion. So, if you sister is not rushing to join, maybe wait another couple weeks. Keep checking the Community here for latest promotion
