I feel absolutely moronic asking this, I can't shake the feeling this is a super simple fix, but here goes.
I have Product A. I no longer stock Product A, and the URL is 404ing. I want to redirect that URL towards the brand Product A is from, or potentially Product B which is similar.
What ends up happening is a new "/productb.2937" URL which also 404s.
Please tell me there's an easy way around this and I'm just having a brain fart!
Maybe you can use the URL redirect feature?
