The only data point I can give is that PP is fairly low down in the list of soaps in the store when sorted by popularity. Who knows whether that’s an accurate measure - I’m just pointing it out.
Independent of that, I’ve learned to buy an extra tub of the soaps that I’m especially fond of if there’s any chance that it will disappear.
Pasha's Prides low ranking when sorting by popularity may have something to do with the fact that it is a new offering. King of Bourbon, according to that list, is the least favorite, but also the newest offering. Most of the older, standby soaps are listed near the top. I would imagine these listing's change over time. Don't know, just saying. Agree with bobmsp. If it's keeping you awake at night, buy an extra tub.
By coincidence, will be shaving with Pasha's Pride today. Good luck and enjoy all your shaves!
