This is not the full list by any margin. If another refunder can do it/has it listed, I can do it (you know who it is). I'll have a more "full", complete list up when my thread is done but don't hesitate to contact me for any refund.
edit 11/24: Have a bunch of recent vouches of places I can do as well but just message me because if someone else can refund it -- I can DEFINITELY refund it.
