SOTP address (State Of The Parts ). oil filters

Not on topic, but sort of because its parts related. I was in a pep Boys store in the Edelbrock section, I bought a chromed steel fuel line because my line into my carb has too much rubber IMO, and the salesman said "this is a discontinued part so you wont be able to return it...' I was like "ok" I get it home and its missing the banjo bolt...sucks so now I'm looking for that, however, what's up with Discontinued Edelbrock parts? The guy then babbled on about supply chain issues, so is it discontinued or is it supply chain?
