I know the CP (checkpoint?) Yellow Snapchats have been around for a while but I have not heard much about their little brother the Green Starbucks. Pill reports has one report of someone earlier this month with them in FL, is there someone else besides Rex selling these?

Do not use the abbreviation CP for check point. Just spell it out people.
