For backers who want to get more than one copies in a pledge, simply add up the number and type it into the "Pledge Amount" field. For example, I want to get two copies of Commander Collection Pack which is HK$ 590 each. That means HK$ 1180 for two copies. Therefore, I choose the Commander Collection Pack and type in HK$ 1180 into the "Pledge Amount" field. After that, just click "Continue" and I can get two copies now.
