My late Mother introduced me to 'Postscript' many years ago. A great source for e.g. exhibition catalogues that were too expensive at the time and other books, especially architectural. Also, an encouragement to read biographies that would normally be overlooked or other subjects. Calendars have proved excellent presents. Administration is good: books arrive quickly, well packed. If one is unavailable, there is a 'credit note' that works the next time an order is placed. While an order is not placed every time their list arrives, this has not deterred them from consistently sending one; it's always a priority to read. 'Postscript' is a welcome resource.
