Spooler

I have no idea what the correct term is but I think it is "spooler"
Anyway, my UP! 3d printer gets the plastic filament from a small spool, and wanting other colors (black) to play with I ordered some plastic filament from http://reprapsource.com/
So how do I get the large spool from reprap source to my small UP! spools?
