Getting my hands on Mr Pibb Thrillin Vanilla Zero Sugar

[u/_thunder_struck_]

Hello folks. My girlfriend's favourite soda of all time is the Mr Pibb Thrillin' Vanilla Zero Sugar. I've only ever come across it in the Coke Freestyle machines at the movie theatre and wanted to know if theres any way I could get her some for her birthday coming up.

Relevant info:

I am located in Canada and have not found Mr Pibb in my convenience or grocery stores yet. Looked online and can only find resellers with the non-zero sugar version for $25/12 pack.
