The only one's I'm selling are the Scary Presents, and a few others occasionally to roll into large.
Last year the small and medium presents were the best to have (aside from LTD), I made so much off those presents I had every LTD and made a couple million coins.
The year before though only LTD presents were good, the rest was garbage, unless you got in on the glitch.
Who knows this year. I'm stacking all presents I can and trying for as many LTD's as possible.
