The Price Of Prom

I`m doing a research paper on prom. Seems like it`s gotten ridiclously expensive! I`m sure you`ve done some looking around at the price of things - can you answer some questions?
1. What`s the best deal you found on anything for prom
2. What was the worst deal
3. Exactly what all does the guy pay for, how about the girl?
4. What`s your biggest complaint
5. What`s your date`s biggest complaint?

Thanks so much in advance for your input!!
