Storage of "Soon to be used" chocolate

I am just getting started and go through maybe even on a busy weekend 5lbs of chocolate. Mostly because I'm testing recipes and honestly the people I work with in my IT world don't need and won't eat much more chocolate than that. Seeing as how they are my guinee pigs..... I mean, the first people trying my chocolate, I try to keep my production scale reasonable.That being said I want to start buying chocolate in bulk, or more bulk than the .5lbs bars I am used to getting around here. Salem so far has thwarted my attempts at finding a local supplier. My rather loquacious question is how do you store your soon to be used chocolate? Soon to be used means usually the next couple weeks. Does it matter? Mainly, I run my testing and playing out of my home kitchen at the moment. I don't have a tupperware big enough to store a 10lb slab of chocolate. If I were to use 2lbs in a day can I break down the other 8lbs into more manageable sizes or will the increased surface area cause the chocolate to stale faster than one large block.Again sorry for the noobish question, but being an egg head I wanted to throw it out there before setting a process that could negatively impact my final product. Thanks for the help.
