This was on sale for 16.99 last month on Newegg. Picked up a copy and can confirm that all the bonus content is downloadable via a single code. Includes:

Playstation Heroes Skin Pack, Uncharted: Drake's Fortune MP Pack, Uncharted 2 Siege Expansion Pack, Currency Multiplier, Golden Guns, Early Access to "Revenge" Booster, Uncharted: Eye of Indra Motion Comic Bundle, Uncharted: Eye of Indra Skins, Uncharted Avatar Packs 1-4, Pinball Heroes - Uncharted

No idea what any of this crap is. Just started playing the first Uncharted the other day myself.
