Giving was probably the way to go in my opinion. The top person had 15,000, I mean, you could just stay AFK for the entire event with 150 bowls and just hope that people enter, you would automatically get 5k candies without even having to lift a finger. I guess you can really only do this though if you have like a ton of gralats you have to waste.
OT: I would save for Black Friday and hopefully Thanksgiving, even though I do not celebrate it. I reckon they will have stock for Thanksgiving because they seemed to have a hat for Bastille Day, which I knew nothing about, but since I know something about Turkey Day, I assume there will be some nice things.
I am saving for Black Friday currently, I really want a nice 2P mount and some other hats/morphs...
