Hide "Apply Coupon" field until needed?

Hello

If you want to apply discount codes. Woocommerce developed and excellent plugin with alot of features ang highly customizable that you can use. Check the next link: https://www.woothemes.com/products/smart-coupons/

Is this the only option? Or might there be a way to do what I mentioned?

Thanks,

Well this option is the easiest and direct the other would modify the code.

I’m not afraid to modify code. Do you know what code to modify?
