FYI For people who preordered this on amazon (full version)

When it was released I got an email with a code for the preorder bonuses, but it was only one code that unlocked the Chrome ICA-9 pistol. I happend to be mucking around looking for my kindle email address just now and found my Message Center, which had two other codes for the explosive duck and white suit in the messages related to your order section.
If you were in the same boat as me and wondering where your other preorder stuff was, its been hiding in there.
