Episode 1 is currently available for free in the PSN store. I have downloaded it and want to purchase the rest of the series. However, I can not buy the episodes separately. The only available option is a $20 bundle. I know I got the first episode for free, but shouldn't the price of the bundle reflect what I already downloaded?
Take iTunes for example. If you purchased a song from a certain album, iTunes allows you to buy the rest of the album at a cheaper price.
