First off - Congratulations!
I have a burning question. Have you figured out how you're going to do shipping and handling? Are you using a 3rd party to do all of the distribution, or do you have the workforce yourself to do it? Kickstarter and Amazon don't do it for you, do they?
Amazon Fulfillment would have cut my profit in half. Yes it saves you time but depending on where you live and where the fulfillment warehouse is, the size of the products you're making, and the cost of shipping them. For my specific case it wasn't worth it. Hiring a few neighbors and working out of the garage for a few days would be far more feasible.
