Do you recall the adage that goes, "A bird in the hand is worth two in the bush?" That may not be the whole picture, though, especially when it comes to hooking the best coupon applications, based on my recent research.

That phrase conveys a cautious and limited worldview that would have been suitable in less turbulent times. However, thanks to technology and limitless opportunities, we are currently living in an era of wealth. Risk-takers and innovators who aren't content with simply having the "bird in the hand" are rewarded in this day and age.

This means that you shouldn't accept the first good offer that you find during Black Friday or any other major sale. Yes, that smartphone sale may seem like a great deal, but what if you could use an online coupon, an app-based cashback offer, or another promotional discount you find on a deal aggregator website in addition to the current sale price?

That "bird in the hand" suddenly seems less desirable than the flock you might have if you're prepared to investigate the "bushes."
