My tried and true Coke Zero fountains are dissapearing around me left and right!!!! What's going on with my CZ fountain flavor???
It's getting serious!!

Had a CZ fountain last week at Five Guys and this week at Pilot.

We have a bunch of Coke Zero fountain kits (signs, etc) in our warehouse. I also saw it at Five Guys the other day - I think it replaced Mello Yello?

Well my local grocery store gas station (Meijer) had CZ dumped on them BY COKE themselves to make room for Pepsi to take half of the fountain.
And then the university I work at lost the Coke fountains to Pepsi as well.
Then the Speedway gas station that carried it also took it out.
The only options I have left charge upwards of 1.80 for a fountain drink and as much as I drink.....

UGH!

Sounds like you answered your own question there - fountain deals changing leading to less Coke selections. My initial thought was that sales/demand was slow enough to prompt fountain operators to change, but after your last response it sounds like some other factors are involved where you are at.
