WAIT A MINUTE HERE! Don't go rushing out to use this free Redbox rental code before reading that it only works at kiosks owned by Albertsons. You can find a full list of stores here, but basically any at CVS, Acme, Jewel, and others should work.
In order to obtain the code, go register to get a letter from Santa and the code will arrive in your inbox within minutes. It's located at the very bottom of the Santa email attachment.
