You can check out Verizon Essentials pack. Has both docks, car charger, HDMI cable, home charger and aux plug. It's normally $100 but can get it on sale for $75 sometimes.
I just saw that for the first time, but I don't need any of the other stuff...just the two docks. So, if anybody sees the $20 deal that they had a few months ago, let me know (or if anybody picked one of those up and would like to sell it to me, I'd appreciate it.)
I looked on ebay and the cheapest one is $55. I can get the docks for $25 each on Amazon so if there is any chance of getting them cheaper than that, I would jump on it.
