If the $$ had to be used practically:
I'd put 1/2 towards my student loan
The other 1/2 into savings! (I know, boring)
If the $$ was to be used not-so-practically:
I'd spend at least 1/2 on new clothes in the coming months (I will actually NEED them, anyway)
And then I'd spend the rest on a fabulous getaway weekend for my husband & me!
