It's so bad and cyclical while just being unavoidable in some areas. On the map, you'll notice how heavily populated northern europe is compared to a lot of sparse areas which have less options. I'm in a relatively normal size town and there is one big box choice and maybe one defunct "local" store that's barely getting by.

I had to beg a guy in a corner shopping center "repair shop" for a small syringe of thermal paste when I ran out (I'm not fucking kidding, there's just no electronics store anywhere nearby, losing Radioshack was fucking hard). Dude at the shop was the only reason I didn't have to go online and wait a week (he wasn't selling it, just had spare for his own use). My trades and hobbies make this a common occurrence throughout the week. Most places now are forced to sell on Amazon to remain competitive (Amazon dominates with shipping cost reduction alone for large items), finding a local or even nationally based company through search algorithms becomes harder and harder as they can't pay to keep up with SEO bullshit. You can try to keep it all legit but with competitive monopolies everywhere you just eventually find out your favorite company no longer really exists.

There are some suppliers I could shop with but each one is an hour drive in different directions and 80% of the time they're ordering the same shit through the same companies I would be using if I went online. It works sometimes, but takes so much effort it becomes it's own full-time job that no one has the ability to keep up with.
