Dry Box Good Deal
I like to buy local when I can - don't mind a few extra bucs to support local business. However, an outfit called Frontier Play - http://www.frontierplay.com/drybox - has great prices on dry boxes and other stuff. I got my 37" aluminum dry box delivered by USPS to my door for $269 - love it. I've got plenty of long trips on a variety of rivers and under all different weather conditions - no problems. The box isn't as "finished" as some others but it is just as functional. The guy I communicated with is Darren Smith - seems like a nice guy. I got the 37" box because it meets the USPS requirements (length, width and height) for low cost shipping. He'll work with you should you want to purchase other stuff and he will put it in the box so you save any additional shipping costs.
