According to Bleeding Cool... https://www.bleedingcool.com/2018/03...-99-3-99-june/
...a number of books (Aquaman, Justice League, Nightwing, Suicide Squad) will end bi-weekly runs and become monthly with an increase in cover price from $2.99 to $3.99. In addition, some of the remaining bi-weekly books will also increase from $2.99 to $3.99 but they don't indicate which ones. The New Age of DC Heroes books will remain at $2.99 though.
from the article...
It seems $2.99 is becoming a rarer price point and I wonder how long until it disappears altogether.In June, Nightwing and Suicide Squad will be joining Aquaman switching from twice-monthly to monthly — and as a result get the price rise from $2.99 to $3.99.
It’s worth noting that it seems that originally the plan for DC Comics was that the twice-monthly schedule at DC Comics was only meant to last a year, but its success saw DC Comics extend that, now heading into its third year. Some books have dropped out, for a variety of reasons.
Surviving as twice-monthly titles now are Batman, Detective Comics, The Flash, Green Lanterns, Hal Jordan & the Green Lantern Corps, Harley Quinn, Injustice 2, and Wonder Woman.
But it’s notable that some twice-monthly or weekly titles for June are now $3.99 including the new Justice League series, as well as Man of Steel.
