BPI Credit Card Promo: Jollibee, Chowking?

It's simple, I have a BPI Petron Mastercard that I use to gas up at Petron (where else) and the good thing about it is that for every full tank of Scarlett, my Innova E diesel, I can eat either at Jollibee or Chowking depending on the BPI promo in place since my full tank is just around PhP2000.00 There's a downside to the lower gas prices with diesel hovering around PhP42/liter, even if my fuel gauge indicator is already lit, and even if I say to the gas boy that it's not automatic filling but sagad (to the brim), my total bill won't fill up to reach PhP2000 to ge myself a free meal at Jollibee or Chowking the downside of low gas prices ;( BPI Credit Card Promo are available but usually late to annouced from January, February, March, April, May, June, July, August, September, October, November, December. I get the latest BPI promo on the arch along Buendia in Makati and probably though their officical twitter and facebook page
