Not at this time.
One of the price points that broke our budget was in the instance where too many backers order several sets of certain items. Under normal circumstances, this would be a good thing. However, if we just barely fund, that would be a problem for us, as we would also have to cover creative and production costs for the Kickstarter.
When we hit our initial funding goal, we are going to explore opening up multiple purchases for all of our backers.
