my b-day is in a 3 weeks. i have only have $100 to spend for every thing. i need help ASAP. my mom and dad are VERY VERY up tight. i will be turning 15.i need help

hey
i'm gonna asume this party will be co-ed..but for how many people?..in a different post i read about this cool party idea..where you could do something along the lines of "Guess how many pieces of candy is in the jar" and who ever is the closet to the right amout gets to take home the candy and the jar..but since your on a budget, you could find old jars around your house(make sure there clear) you could put buttons or beads or rice in them (this way you dont have to spend so how money on candy) and have your friends guess the amount of the buttons/beads/rice..and who ever is closet gets a prize, or maybe you could go out and buy a cheap bag of asorted candy (where i live we usually find them at paper warehouse or walgreens or wal-mart)...if you can have your party at home you could go with a "dress as a famous person" and then you could have a contest to see who has the most creative costume, best, most funny, most boring, and you could also hand out prizes..if you need more ideas or have questions i'll check back soon
