Maybe they’re using a similar system to O2 sensors in SCUBA rebreathers. 3 identical sensors measure the same thing. When one sensor drifts, the computer uses the value from the 2 concurring sensors, and throws an error to let you know something is wrong.

That system is life-critical, so these beans must be about the same importance.

This is a post right now because prices have (hopefully) temporarily spiked. My grocery store had a sign apologizing, blaming avian flu+high demand, and promising to keep their process competitive. I think 2 bucks is normal for us too but right now they’re over $5.

Extra, the green mint is my favorite but every once in a while I’ll pick a different color. To me, extra is the only gum where the flavor lasts longer enough to be worthwhile.
