I had 2 boxes just up and vanish on me without giving any gift.
Seriously, though, out of 60 odd presents, I got 5-6k gralats, with between 250 and 500 in each one that was giving gralats. Not even discussing recycled foods, I got some decent hats (some one obviously gave me a couple cute gifts), a santa bomb, pogo, bouncy.... light show... a mini spider pet that looks like it has a case of the derp... oh yeah book stand...
What do we do about the ones that just vanished?
