I keep spare computer parts on hand because driving to buy a part costs me at least half a day and a hundred-plus miles each way -- if the thing that I need is even available in the nearest burg of <60k souls. If it's (as usual) not available there, driving to the that thing is four and a half hours each way. Either way, I'm risking mountain two-lanes for the first forty miles, dodging around livestock, big game (antelope, deer, elk, moose), Frackwater Jack the burned out diesel dummy, flatlanders who think that they're road racers, and for about half of the year, possible snow and ice. Somehow I'm ahead of the plow about 90% of the time. :D
When some random cheap part (PSU, fan, RAM module, coolant pump, etc.) dies, I install one from my office closet and order up a new spare. If it's a CPU or motherboard I'll be forced to hijack my wife's workstation for a bit, but once my garbage is on there I'm not in a rush for parts any more. It costs more than making Bezos richer, but it's cheap enough insurance to keep the billable hours rolling.
Just so it's said: I'm not bashing you or anyone else who patronizes monopolists. Ain't my money, ain't my life, ain't my thing to think about. I'm just spewing an idea at the internet.
