Sorry, I'm feeling a bit lazy today, so I"m going to do this all in one chunk.
Kellogg's: 150 points for entering codes KELLOGGSREWARDSU and RESCUEYOURPOINTS. I can't remember how much each code gives, so try them both.
My Coke Rewards: Head through the link and invite five friends. Once they accept, you'll get a coupon for a free 20 oz at Target. Hey, you must know five people or have five email addresses.
Disney Movie Rewards: Five points each for codes FEAST and BIGHERO6.
