An update on the boxes (as I've opened quite a few). By far the average gold drop is around 20,000-30,000, but I have gotten 1mill, 5mill, 10mill, 50mill, 100mill, and even 200mill. I have also gotten a star charm twice. The usual GC drop is 1 GC, but I have also gotten 5 GC, 10 GC, 15GC, and 30 GC drops. Probably more importantly, one of the banners I came across last night said that the boxes contain the chance to win "up to 10,000 GC!"
A part of me is thinking the GC drops in these boxes might be the replacement for GC dropping in the Daily Chance (which they took away due to glitches). It just seems like an easier option for them. These boxes are a lot like the DC, anyway, but without gold shop items grants.
Another little note: so far as I can gather, you can collect three gift boxes on your account per day. (I'm still testing the 'per day' part, but it seems to be the case.) This means that you can click the same grant link three times, but then you have to wait until the next day to click another and get something for it. Even if you won't receive more boxes, the grant links will still appear.
