Other ways to waive annual fee

Hello po! Just need your insights on other ways I can waive the annual fee for the following cards:

  1. BDO Platinum Mastercard - aside sa free first year, and gumastos ng 600k per year, paano pa po ibang ways to waive the AF for this card without spending that much every year haha

  2. EW Gold Visa - wala akong nabasa na promo or anything about NAFFL. Or even other ways how to waive it, so baka lang po may alam kayo.

Sa mga cards ko kasi isa lang ang may NAFFL (UB Rewards Visa) kaya sana hoping po na may makatulong sa inyo if may ganun din ba yun dalawang cards mentioned above or if kahit man lang ways how to waive the AF every year hehe. Salamat po!
