Well, I'm now convinced that Scottish genealogists have a hard time.
Looking up the website I find that the cost of a certificate, ordered by post is £13, as opposed to £7 in England.
Actually you do not have to pay £13. If you want a copy of a 1923 birth certificate and can't get to Edinburgh or Glasgow, you can get a professional searcher to transribe it for you for a pound or two. Still far cheaper than having to send away and pay £7. There are links on the GROS web site
http://www.gro-scotland.gov.uk/index.html to lists of searchers.
The difference is that in England you have to send away for every certificate at a cost of £7 a time. Also the English indexes may be available freely, but until FreeBMD is complete they are a pain to search as you have to look separately at four different fiches or images for every year.
I pay £17 for a day in New Register House, which would not quite buy me three English certificates. For this I can look up any certificate I like, using a fully computerised index, view any certificate from 1855 to 2004, transcribe any I am interested in, print off the image for 50p, or finally order an official copy for £13. In a good day I have been able to look up 200 certificates, which would have cost me £1400 in England. A normal day's haul is 100 certificates, for which I'd have to pay £700 in England, with no guarantee that they are the right ones.
Also the information on Scottish certificates is much better. A birth certificate tells you the date and place of the parents' marriage; marriage certificate tells you the full names of the couple's mothers as well as their fathers; and a death certificate tells you the names of the parents of the deceased. All of this, plus the better accessibility of Scottish certificates, makes life for Scottish genealogists much easier than English ones. Don't knock it; we do not want the GROS copying the GRO.
