https://www.crowdtilt.comhttps://www.crowdtilt.com/campaigns/dragoncon-group-passesif you need to crowdfund a party, collect money for a room multiple people are using or whatever, crowd tilt is waiving their fee til 3/July/2012 with the use of promo code Fireworks2012 it worked on mine, that i started before the code went into effect.
also I am late in getting memberships and am trying to crowdfund a group discount. so if you drug your feet, feel free to join the fun, your card wont get charged if the goal is not met.
(the credit card companies will always get their fees)
