T.H.
I have a business called Whisper Parties and we provide a tasteful presentation of adult products in clients homes or at a bar. I have done several Bachelorette Parties and when my presentation is over, all of the guests put money in a kitty as they place their order and then when the bachelorette makes her purchase, she pays next to nothing for the items she wants.
Many women (bridesmaid, maid of honor etc.) plan this as part of their night and have the presentation early so they can go bowling or out to a bar of club afterwards.
You can go to www.whisperparties.com to find a representative near you or you can contact me in Southeastern Wisconsin at www.myspace.com/whisperparties.
Good luck and congratulations!
