I do know that in the uk, a good access point for younger readers to marvel and dc are the licensed reprints from panini and titan
Available widely in big chain stores and about 3 to 4 floppys of content for around 4 to 5 pound
That's decent value for material around a year or so old, the marvel ones are currently doing secret empire
Working with youngsters, this is what most tell me they read and go to if a movie catches their interest, it's not a 15 to 20 pound trade
dc move into Walmart looks smart imo
