What's the better idea?

So my Musical Theatre teacher approved of me performing Home from the Musical Wonderland! I'm so happy and excited to get to perform it in front of people!

I now have two options on how to obtain the sheet music for the performance but I'm not sure which one I should do:

1) I could purchase the vocal/piano book off of Amazon for $16.44. I wouldn't have to worry about shipping because as long as it comes in before school starts in September, I'm fine.

2) I could make an account on Scribd and use my free trial to get it without purchasing it. Only thing is I'd have to ask my mom for her credit card information to make the account, But i would be deleting it right after printing my music.

Which one should i do? I know most people would be like just use the free trial! But if I cough up the money I could have the whole book for myself! I'm not sure what I should do.
