This statement is taken from the SPCK website:

‘SPCK would like to emphasize that they do not own, manage or otherwise run the Bookshops which transferred to SSG’s Charitable Trust in October 2006.

Saint Stephen the Great (SSG) was contacted by SPCK’s lawyers in October 2007 concerning its use of the SPCK name for what used to trade as the SPCK Bookshops group.
In October 2007, SSG put out a release clarifying that from 1 November the bookshops would be trading under the name Saint Stephen the Great. ‘

I find it quite interesting that despite this I haven’t seen a store with a large ‘SSG’ sign outside it…I also would like to urge readers if you have a SSG alongside another Christian bookshop where you live to use the other one…alternatively shop at Wesley Owen online
