You could do an 80's movie themed night at your house or go see a movie as a group. Or rather than a 'party', do an activity like bowling or ice skating---neither of those are expensive.

My birthday is in april and I need some ideas on what to do for a party. I will be turning 14. I don't want it to be to expensive and I will probably want to have some guys at it. It also needs to be it if the house, so no sleepover! Hope you can give some ideas.
