Great conspiracy theory but it doesn't work.That would be great however, one of the ideas put forward was that they will drum up as much money as they possibly can. Say they get the total to about 20-30K. They will then add the money they've got waiting as a deposit to this total (via anonymous donors) so that they meet the target, and therefore get to keep all the money from Kickstarter. I honestly wouldn't put it past them. Watch this space.
Kickstarter takes 5% and payment processing fees are 3%+£0.20 per pledge. Dulmar and Tatty would have to pledge about £32,000 before breaking even by paying the rest of the £390,000 from their own pockets. They are currently at £6,716.
