Upgrade iPhone 5s to iPhone 6?

I currently have the iPhone 5s and I love it, but I very much want to upgrade to the iPhone 6 or 6 Plus. I'm currently with Verizon and I understand that some carriers allowed clients to trade in their old iPhones for the 6. But from what I've seen, all promotional deals are over. I was wondering if anyone knew of any way I could trade in my iPhone 5s (Great condition, gold, 16 gigabytes) for the iPhone 6, for a great price? Any answers are appreciated.

Don't get an iphone 6, they break very easily, they even bend in your pocket, if you don't believe me go look on youtube.
