Would also be a smart move if you already have outstanding finance at higher terms, either loans, hp or credit cards etc to to take the loan and pay it off.
I'm keeping hold of the money for a few months to see what happens, i think it would be daft to blow it right now but at a years interest free no harm in taking the loan and sticking it in savings for a year, if I decide I don't want it then just give it back.
