Let's just hope that the tremendously helpful ones, like Birmingham, won't be prevented from offering free checks and searches. Without this, I wouldn't have contemplated buying some of the certs I have.
I really think not enough market research has gone into this. There are lots I would buy if they were cheaper. Just one example, there's a couple who died in their 50s, in the same quarter: was there an accident and one lingered longer? was it an infectious disease that claimed both? or did one not want to go on without the other? I don't need to know, but I'm curious. I'd probably have bought both by now if they cost a fiver, as it is, I haven't and certainly won't now.
