There was a feeding frenzy on this book the moment the Black Adam actor The Rock was announced as the antagonist in the Shazam! movie. Prices have been crazy ever since.
While Shazam! #1 was initially a big gainer, copies flooded the market, forcing prices even of nice 9.8s with white pages lower as more supply choked off the demand.
Shazam! #28 is a different proposition. Later in the run (never a very popular series), lower print run, consigned for many years to dealer dump bins, and therefore seldom found in high grade.
Look for a 9.6, or if you can afford one, a 9.8, and don't be surprised if you can pick up copies at garage sales. Shazam! #28 just doesn't stick out the way a Detective #27 or Action #1 does.
