Which is bizarrely hard to find. All the other MMPB SCE books were a couple of quid new on Amazon Marketplace, but No Surrender was like £20 second hand. Fortunately I managed to find one for a reasonable price on Ebay.
This was good to know. I checked Ebay and the cheapest was $20+ shipping. I went to Amazon and there was a used one for $2+ shipping and the rest were $20 minimum. So, I snatched it up.
