Starting this month, DC and Walmart are selling "Giant" 100-page magazines. They each feature 3 re-printed comics and either a new story or some kind of feature article.
I just read Batman Giant #1, which has a new story about Batman looking for a kidnapped girl. Based on the costumes and vehicles, it appears to be set in current Rebirth continuity. It's pretty good and will conclude in Batman Giant #2.
I dunno if anyone else is keeping tabs on these DC Giants, but I picked up the new Batwoman - Supergirl: World's Finest Giant #1 today. It's worth the five bucks.
