I used to walk past Postscript's London base on my way to work, after I started buying from them, and I've been doing so regularly ever since, even though I've retired to the Cotswolds. I use our local library as well, and it's often a question of whether I want to retain a book or not, although there are plenty of charity outlets for those I still decide to buy but then not to keep; often attractive at Postscript's prices. I occasionally buy cut price books elsewhere online, but over time more come from Postscript than anywhere else: both book quality and delivery are reliable. Keep up the good work!
