I decided to try Browns-books on Saturday because they had both Moon knight epics for 20 quid including postage. They arrived today so shipping was really fast.
The quality is way above the listed "acceptable", I think these are copies that got damaged during transit. Vol 1 is a bit worse for the wear but vol2 is in really nice condition so for this price I'm glad I bit the bullet.
worth checking their amazon store, still have a few deals left (search engine is terrible though)
