I went wild about 15 years ago (mid-life crisis?). I made an arrangement with a guy in the GC guitar area down in So. Cal. who wanted to move up: "Give me whatever I want for $2 over cost and I'll buy a lot from you." He made manager and, since I hadn't been keeping track, I was shocked when he said I'd spent over $40k that year!
After moving to the Pacific Northwest, I made a similar set up with a GC guy here and bought a lot, but nothing like in California. This guy did even better than making manager, he got a job at Apple Music - LOL.
