Marvel Digital Comics?

I've been flirting with the idea of giving a couple Marvel titles a try. I thought it'd be a good idea to go digital but the prices! I know Marvel is mainly $3.99 compared to the mostly $2.99 at DC. But the DC comics I get digitally get go down in price over time. I was able to read most of Earth 2 at a good discount, some single issues at $1.99.
