> books are cheaper than a Doordash meal or a computer game we buy and never finish. Would the average person really read more books if they were $4.99 instead of $29.95?

As a data point I'm reading some series I enjoyed the first 2 volumes of. I just picked up the next 7 ones because they were there and each of em were ~$5. Wouldn't have done that if they were $30, and I'm not guaranteed to get to the end!
