My understanding is that it takes way longer than 2 days after a Kickstarter closes to get your money. Sounds like they can't withdraw any money for 14 days after the KS ends according to their FAQ.

"US-based projects: If your project is successfully funded, funds are transferred directly from backers' credit cards to the project creator's Amazon Payments account. There is a 14-day window for collecting and processing pledges. Once the 14-day window has passed, you can transfer funds from your Amazon Payments account to your linked bank account."
