Here's a few pics of my "collection" - certainly not the prettiest corner of the garage, but hey, it works.
the four shelves on the left contain mostly my stuff - assorted samples, ONR, odds and ends junk, interior towels, window towels (for use with glass sealants but not window cleaner), terry towels, interior brushes, interior cleaners and protectants, my G110v2, and extra stuff (mainly additional of something, like if I have a second bottle of DP Auto Bath it goes somewhere on that shelving unit)
wheel and spoke brushes
Cobra towels and a few CG towels are in the green bin, edgeless towels and Supreme Shines are in the bottom clear bin, clean foam applicators are in the top clear bin
waxes and sealants, extra wash mitts, extension cord, Autogeek apron
glass cleaners, clay bars, clay lubricants, car washes, spray waxes, quick detailers, waterless washes, paint cleaners, polishes, and compounds are on this shelf
pretty much everything else is on the bottom two shelves - glass towels, waffle weaves, door jam towels, foaming carpet cleaner, APC and APC+, tire dressings, trim dressings, plastic cleaners and sealant, Brinkmann, compressed air cans, TAW and DP Cleanse-All, large bottles of car wash, degreasers, assorted tire and wheel brushes, tools (hose nozzles and connectors, foam gun, etc.), and gallon jugs. Polishing pads and extra sprayers, tire swipes, and microfiber applicators are in the bottom gray bin on the right. In the top bin is Meguiar's stuff I take to work at the Honda dealership with me.
