Spend it :)
If I won it......I'd give almost half to my parents so they could do whatever they needed with it and then save the rest to help buy a house for DF and myself.
New car! Or atleast new to me!!
It would pay my house off and still have some leftover.
Pay off most (if not all) debts, get some mechanic work done on my Explorer,open a trust fund for my kids and save.
Pay off our bills and probably buy a used car. Save some too.
