printgreener.com sells software at $29 whereas purifyr.com charges for $299 for the developer API account. (Hmm, seems like I haven't made it clear enough, maybe?)

As for the "green card", yes, that's right. Their whole message seems to be geared towards this. A good execution.

"you hardly tell the user why they would want to do this." Hmmm, I think you're right. Let me think of this and give the homepage one more shot.

Thanks a lot, rythie.
