It might be because graphic novels consolidate multiple single issues into one volume. This saves on distribution and marketing costs for publishers, which can be reflected in the price.
One reason could be that graphic novels are usually produced in larger quantities, which can bring down the production cost per unit, allowing for a lower price.
Maybe it's because single issues have to cover the cost of individual printing and shipping more frequently, while graphic novels have these costs spread out over a larger collection, making them cheaper to sell.
