I use Postscript on a fairly regular basis and have been doing so for many years. Their website is easy to browse, well presented, and I like the selection they have and the prices are very good. The condition of the books has always been excellent and the way the books are packaged for delivery has never damaged them, which sometimes happens with other retailers who overstuff small packaging. I also appreciate that all of the packaging is biodegradable. Postscript sends a small catalogue each month, advertising their books, and it's a well produced little magazine. Overall, I highly recommend Postscript.
