This is primarily for the relatively newer items.
TF2: The new cases (Powerhouse and Concealed Killer) along with the weapon skins.
CS: GO: Music Kits, Cologne 2015 Stickers, Autograph Capsules, music kits and some new skins.

Hopefully the dispenser.tf item library can be updated such that I'm able to deposit newer items into my VIP bot, thanks.
