Almost every error, crash, problem, or compile problem I've come across has had at least some discussion of it, often including a solution. If not, you're already on the plug mailing list, so you have a wealth of people here willing to help you out, provide expertise, advice, and try to search for a solution yourself. They're at least as good as what you'll find at Red Seven or other places.
Newegg, Frys, and other places are good sources of replacements/upgrades if the problem is in the hardware.
That's why, even though I liked the concept of a linux support store, I never had reason to be a customer. Any problem they could fix was either one I could already fix myself (with plenty of googling and trial and error), or one I couldn't afford to fix myself, much less hire someone else to do the same thing (hardware errors).
