I like the kind of retro looking covers, but sure don't like the prices. $14.99 list price, which equates to $13.49 at Sony and $9.99 at Amazon and B&N. Looks like those are the only three places to get them. To be fair some of those old titles go for pretty good money for used print copies, but it'd be nice if these were a bit cheaper than they are. I wonder how the $14.99 list will compare to the cost of their POD copies when they do them.
