Most societies require you to pay upfront. But if you don't bring money or forget to, societies/cubs will be around for a couple of weeks around manning for you to join!
Last year i joined:
Co-op life membership Membership ($25) - 10% discount.
Comsoc ($8) - Comsoc Formal, BBQ's, Yum Cha Outings, Pub Crawl, Cocktail Parties and Seminars/Lectures from large companies. Oh and a bag of goodies when you apply.
AYBC ($10) - this is the Australian Youth Business Council. We had Parties, BBQ's, cruise, formal etc
Anime club ($5-$10) - weekly/monthly anime screenings.
I wanted to join more like subski (most people join cos its the club with the wildest social scene) and Select Marketing but couldn't be bothered at that time, but i will this time around!!!
