Hello Jean,
I have lots of Wills which I downloaded quite some time back before SP took over the Wills.
And I'm a long-term user of SP for OPR entries, for BDM transcripts and for censuses (as my credit card records clearly show
)
But, as it happens, yesterday was the very first time that I downloaded a Will from SP (I'd done lots of free searches for Wills on SP but not previously downloaded one from SP). I had credits remaining but, like you, found - to my great surprise - that there didn't seem to be any way to use them for purchase of a Will. So I just went ahead and paid up my 5 pounds by credit card.
I've just checked out the SP site and it does actually refer to this. But I had to search around quite a bit in order to find the relevant information.
In the 'Help & Other Resources', go to 'Customer Information', then to 'Payment Process'. It reads:
Please note: Two separate methods of payment are employed on this site: Access to statutory, old parish register and census records is based on a system of credits, purchased through a card transaction or a Voucher, but payment for images of wills & testaments is done directly through a card transaction. Access to the wills & testaments index is free. The point of my post is that SP really does need to highlight the two different payment methods.
I've found that SP is pretty reasonable so I hope they'll refund those credits (if you wish) and then you can just go ahead and use your card to purchase the Will.
Regards,
JAP
PS: I use Direct Download and have never had any problems zooming in and out of downloaded Wills. (To find what method you are using, login to SP and click on 'My Details' in the line of small print near the top of the screen. On the screen which comes up, scroll down to 'Image Viewer' and there is a drop-down menu with three choices - Direct Download, ActiveX Control, and Java Applet.)
PPS: Scottish Wills in the 1800s are usually easy to read, and don't often include words which are specific to Scotland.
