We have a couple of copies of issue 5 in the back issue store but there seems to be a glitch and these aren't showing. I'm trying to get that rectified now.
You can order it by telephone +44 (0) 844 322 1237.
I've actually discovered a few copies of issue 8 in storage too so I will send those to the store today. If you can wait a few days before you call the above number you should be able to order both back issues together.
I hope this helps, if you require any further information please don't hesitate to ask.
