If they agree that it is a gift, the tax and duty is based on e.g. the average price of the item or similar items currently on the market. We are speaking roughly 30% extra on top of that price. But that is not all. In this case that market price is most likely too high to begin with. The game does not have as high a budget as other boxed non-downloadable games. As backers, we should have the game for 'prime cost' not retail price. That is why we are hoping for InExile to mark the value. In any case, this is not so bad an option and it is justifiable to pay these taxes.

Most importantly, customs might judge that it cannot be a gift at all, because evidence within the packet itself or on internet states that we have transferred money to the sender in order to receive this shipment. Our legal system does not know of these kinds of donations to companies that then give us rewards. Charity is different: Here, one must get a permit to hold a fund-raising campaign and that cannot be obtained for any other than humanitarian purposes. And a specific requirement for fund-raising campaigns is that the backer does not receive any form of compensation. All this may lead to that they consider the donation as a purchase and the whole pledge amount becomes the price of item. Then we are talking about that 30% on top of the pledge which can be quite high in relation to the reward. This is a very problematic scenario.
Finally, if InExile marks the packet clearly as a purchased item for specific price, then InExile might have to deal with some nasty legal issues about donations and taxes related to those donations etc. This depends on local laws in the USA I am unfamiliar with, and cannot comment further than that.
