I have 12 soaps and 4 creams. Williams Mug Shaving Soap Kell's Original Hemp Black Tea Van Der Hagen Deluxe Ogallala Bay Rum and Sandlewood (sample) Ogallala Bay Rum (sample) Ogallala Bay Rum Sage and Cedar (sample) Ogallala Bay Rum Lemon Grass (sample) Ogallala Bay Rum Unmarked (sample) Mama Bear's Awakening's Mama Bear's Sandlewood Vanilla My Time Bath and Body Menthol 8/10 Louisiana Toilette Soap Arko Commando True Blue Spa Shave The Day C. O. Bigelow The Real Shave Co. I have no idea how long a puck would last. I think last year, 2 pucks of VDH lasted me the entire year. That was when I was still using disposable razors.
For about 8 months I alternated 50-50 between Williams (that was about half used up) and 3 TSD samples, finishing all. Under constant use, that translates into 8 months for a full puck of Williams, and about 1.25 months each for the TSD samples. I now have 4 soaps in the rotation: Tabac, Arko, and 2 TSD Samples. I plan to keep that lineup for a good while, and focus my experimentation on blades, razors, and aftershaves before settling those down to a vital few, allowing of course for necessary variety.
