Nice deal. If you can store it, do it. Uncrushed, you can have it hanging around in an airtight container for quite a few months, stored in a cool place.
I stopped buying bulk 2 row when I wanted to experiment with other base malts. I don't have a crusher, so I would crush the whole thing at the LHBS and then I had to use it up fairly quick. Now, I just buy per batch.
