Just a little tip for the people who haven't thought about this:
Every Christmas you can open presents under the great Christmas trees in your factions Capital City. Now, most of these rewards are either crap or BoP, aside from the pets! Every level 20+ character can go and get the Gaily Wrapped Present.
It contains 1 of these pets:
Snowman
Green Helper
Jingling Bell
Red Helper
Just log on every character you got above level 20, open the present, send them to your bankalt or main for convience, and wait some months. They'll go easily for 300-600g! I've sold around 8 of them last year (around 4 months ago), and they've all sold for 450g, since thats what I put em on AH for.
(Inb4 flames: even though you gotta wait months, it just requires a few minutes of work)
