When it comes to hardware and brushes I've focused on just what's needed to provide my desired range of utility. For me it's three brushes, two synthetics that I rotate so they are completely dry when used and a boar for my hardest soaps. Same for razors where my three are all I need to provide my desired range of mild to mid-range aggressiveness.
Regarding soaps an creams I've gone a bit broader with around a dozen different soaps, some custom blends and four creams that I rotate between. These are commercial products such as Mitchell's Wool Fat, Tabac, Cyril R. Salter, D.R. Harris, Proraso, Arko and Williams soaps and two creams each from Cyril R. Salter and LEA. When I've found something I like I've purchased backup stock for my hard soaps especially tallow based products like Williams and MWF. Up to just one back up for my creams as the shelf-lives are shorter. The variety from my soaps and creams makes this hobby more interesting.
I rotate among three "primary" soaps in open shaving mugs (currently Razorock What-the-Puck Black, Tabac and a custom blend) and roughly once a week use a different secondary soap or cream kept in resealable containers. When I 3017 a primary one of the secondaries takes its place.
Narrow and deep for my blades with good inventory of three brands including Dorco, Astra and Derby. Likely have soap and blades to last a decade or more.
