Anyway, DC have a seven day Superman/Doomsday sale on, broadly containing the following collections:
The Death and Return of Superman Omnibus (including the Death of Superman, Funeral for a Friend and Reign of the Supermen)
Superman/Doomsday (including Hunter/Prey and the Doomsday Wars)
Return of Doomsday
Reign of Doomsday
For some reason Superman 77 from the Omnibus is not in the sale (although the rest of 73-82 are). The Legacy of Superman ( also in the Omnibus) is not yet in the digital store, and I also can't seem to find the Doomsday Annual from the Superman/Doomsday collection. But Justice League 70 (not in the Omnibus) is in this sale.
I've got all these in book form, so I won't be double dipping today.
