Is there a way to run Facebook ads on a schedule like daily from 2PM - 10PM, but on a daily budget? I know it's possible to do so with a lifetime budget, but I don't want to set a lifetime budget for ads I'm testing. I want to optimize my ads to only spend money when people are actually going to be interested in buying. I think this is possible through third party applications, but the ones I've found were very expensive to use. Does anyone have a cheap alternative or a workaround to using a lifetime budget?
