@Adw5088 I once had a guy tell me Pibb was a “poor man’s Dr. Pepper.” I then asked why the two were the same price.

Drank some Mr Pibb today and noticed it’s described as “Spicy Cherry Soda”. Guess they got tired of the label: “Poor man’s Dr Pepper”

Pibb Xtra: the poor man’s Dr. Pepper. Not counting all those other knockoffs, like “Dr. Thunder,” of course. Those aren’t sodas!

Mr. Pibb is a poor man’s Dr.Pepper. The only reason to know where it’s distributed is to boycott anyone who sells the abomination 😬

When I was growing up Mr. Pibb was a poor man’s Dr. Pepper.
I acquired quite the taste for it.
