Most payment systems will allow sellers to issue refunds either free or with low flat cost (e.g., $.30). But Kickstarter is a different beast. I think they're probably only losing 10%, but maybe they're factoring in the cost of sending you money or if they incurred currency conversion or banking fees. Ethically, you presumably wanted to support this company, but now you're actually asking them to lose money. If you really just want your money back, in addition to chargebacks, ask your credit card company about your coverage in the event of refund/re-stocking fees. Some cards offer protection to cover you in this situation. Also, when initiating a chargeback, you can ask the credit card company to do a conference call with the seller and that might persuade them to do 100%, to avoid chargeback fees and potentially losing their processing account.
