I am the cost of every choice you make but I am never the thing you buy

I don't talk much, but I sure can scream, Especially when falling into a vast ravine, I play with time, wind, and masks a lot, If you think that I'm Zelda, I'm sorry, I'm not

I am at the very edge, a tiny helping hint. I am a handful of pennies given to one who serves. Five of me sit upon each hand.

I can run but cannot walk. Without me, your food tastes bland.

I can start a fire, Or flash from a wire. If you want to make your mark, You'll need a big idea, inspired by a blank. What am I?
