Yeah, they've got a term for that. It's called price fixing. It's illegal.
That may well be the case today, but it didn't use to be.
Strange, though, for a system that was apparently so flawed, many more shops existed than today, many more people had jobs in them and all the pros or amateurs who wanted stuff had it. As I say, strange.
But bless you, it's my problem: I have this Golden Syndrome, don't you know? Even, more strange, I lived the time when Golden existed. But what would I know, it's only experience, after all, of both then and now.
