don't pay £23 per certificate.

from my email:-

Dear listers,

It would appear that a bogus certificate ordering website has sprung up

they appear to charge £23 per certificate. As anyone ordering from the
official depts will know, they only cost £7, and sometimes a search charge
is required of £4. Please alert your fellow genealogists to this,
especially the newbies.

kind regards, Jon
