Electronics are a different market than the one that McMaster serves. Frequently at Digikey, you need an exact part number from a specific manufacturer. Or, if you're buying parts at scale, you might be quite price-sensitive.
At McMaster, there would be one 555 timer, one utility op-amp that implements the LM741 spec, one low-noise op-amp, one 5V regulator, etc. They would all perform at or somewhat above average, but you wouldn't know precisely what you were getting.
There probably is room for a McMaster-like Digikey (or a simplified Digikey storefront for those who aren't picky about details), but it is unclear how large its market opportunity might be. It might look kinda like SparkFun.
A lot of the time, details in electronics really do matter. I think I've ordered almost every variation of the LM35 temperature sensor over my career. Sometimes you care more about price, sometimes you care more about accuracy. McMaster would probably only stock one of the grades, not sure which.
