They're only precious if you know what you're doing. At one point, possible all points on a line, I didn't and don't.
I have finally figured out how to install the certificate (call it A) that was in my account at developer.apple.com. But before I found the cheap route, I created a certificate (call it B) that I fear I won't be able to use in 3 years when A expires. I will have forgotten everything and go through this whole mess again. So, I never intend to use B and would prefer to not be tempted to even try it.
