What if digital books were priced at $1.99 and went down to a dollar after say 3 months or even 6. Would it change how you bought comics if you normally buy physical books? Would you buy more comics if they were more affordable?
We know it's profitable. They don't lose money on .99 cent sales, or $3.99 for a 25 dollar trade sale. A big part of the price starting out full retail is to keep comic shops happy, they also want to maximize profit I'm sure, but would it be made up in volume? Marvel will let you read everything they publish for as little as $5 dollars a month if you catch the yearly digital unlimited sale, you just need to stay 6 moths behind.
I don't think anyone is really taking advantage of digital. At one time people from both companies said they wouldn't ever release the same day as print, all it took was Archie breaking the ice and everyone followed suit. Older books never make the top of the sales charts, so I don't think they sell well after the first couple months, why not entice a larger pool of readers. If new readers is the goal, and digital is the future, they are failing. I think being able to follow DC at half the price of Marvel would be a good way to grow long term customer loyalty.
