为什么要每天分享？
you don't have to share daily, but if you do share about the giveaway every single day, that's more points that you score. that means, when the rafflecopter ai randomly selects a winner, you have more chances of winning because you scored more points.
i hit a button called "select winner", and a winner is randomly selected 通过 the rafflecopter ai. for this particular giveaway, i do it three times and winner's will appear on the widget below when chosen.
