Could someone from the UK help a member from the US?

Hey there.

I'm looking for these Storm condensed novels by Don Lawrence in paperback. If any UKer is near a comic book shop or a regular book store, can you let me know if they are available? And if so, how much are they asking? I'm looking for the versions in English text only. Not looking for first editions.

Book 5- The Battle For Earth (1979)
Book 6- The Secret of the Nitron Rays (1979-1980)
Book 7- THE LEGEND OF YGGDRASIL (1980)

Book 9- THE CREEPING DEATH (1981)
Book 11- THE LABYRINTH OF DEATH (1983)
Book 12- THE SEVEN OF AROMATER (1983)
Book 13- THE SLAYER OF ERIBAN (1984)
Book 14- THE DOGS OF MARDUK (1984-1985)
