It makes you pay for 30 credits though which I don't need and I have wasted a lot of money on this website in the past. Why they can't have had a monthly subscription like other sites.
The GRO in England and Wales doesn't have a subscription system, and a certificate costs £6.00
GRONI in Northern Ireland doesn't have a subscription system, and IIRC a certificate costs £2.50
New South Wales doesn't have a subscription system, and a certificate costs AUS$35
Victoria doesn't have a subscription system, and a certificate costs AUS$22
Queensland doesn't have a subscription system, and a certificate costs AUS$54.40
Western Australia doesn't have a subscription system, and a certificate costs AUS$36.00
New Zealand doesn't have a subscription system, and a certificate costs NZ$25.00
Manitoba doesn't have a a subscription system, and a certificate costs CAN$30.00
None of the subscription sites holds a full set of certificates for all these places, and in fact there are relatively few places that make their BDM records freely available online - Republic of Ireland, British Columbia, Ontario and one US state, I forget which, are the only ones of which I am aware.
30 credits on SP will cost less than one certificate from most of these places, and you will still have enough credits to get another 4 certificates or original census records.
Furthermore, Scottish certificates are far more informative than English, Welsh or Irish ones because they normally tell you the full names of the parents of the deceased including the deceased's mother's maiden name. So in spite of being cheaper they are much better value for money.
And you don't need to wait for the information to arrive later or by post - you get it then and there.
