Seems like it was "100 years ago" (really just about 60) that I bought a "big set of glass cartridge fuses" so I'd have a replacement for anything I needed... About 10 years later, after only using 1 or 2 of them, the industry changed to using "regular size plug in fuses" so I bought a set of them. Again, so I'd have any fuse I needed and only used 1 or 2 of them... Then, about 10 years ago, the industry changed again, to the mini-plug in fuses, so I bought another "whole big set of fuses so I'd have any size I might need"....
Now, I'm waiting for the industry to find another way to make my "vast fuse collection" obsolete....
Ironic part of most of this: I've had more issues with "fusible links" than I have with fuses and NOBODY makes a "comprehensive set of various size fusible links"..... Maybe somewhere in all this is a "hint from the industry" that anything you buy in bulk is going to make more money for them than it will convenience for you.....
