Halo players, Appraise these Real Quick :)

Guys, I ordered Halo 4 and it will be in tomorrow, and it doesn't come with any codes. I'm going to purchase some codes, so Please appraise How much each is worth so I don't overpay.

Specialization Codes:
Arctic BR codes:
Forrest Armor Code:
Fotus Armor code:
Locus Helmet:


Also, if you're selling any, let me know. Thank you.
