500 Pesos of Noche Buena

For those that know me and taste of movies, the title itself is a pun on 500 Days of Summer.
This is the social dilemma that we are in right now - kasya nga ba ang 500 pesos for Noche Buena?
But I think we are asking the wrong question. Rather than ask kung kasya, isn't it better to ask how much should we be spending for it. Or better, how much should you spend to make it a good Noche Buena.
Quick disclaimer: this episode won't dip into the political side of things.
