I called to see if they are going to bring back Pepsi Throwback Permanently and they said they are taking zip codes. So, If anyone is interested in calling and giving them your zip code, if they get enough maybe they Will make it Permanent. Please Call them it might make a difference! Here is Pepsi's phone number. 1 (800) 433-2652. and just tell them that you are calling about the Pepsi Throwback and that you would like to add your Zip code. Thanks!
