On the checkout page, there is an $80/year option. I just didn't want to complicate the marketing page, but it seems like I should add the optional yearly pricing there.
I second this but at the same time the founder has a point. Since the average user can't create a blog with GH Pages or whatever else for free, he'll be willing to pay $8 for this product. The average customer won't be from the tech space and $8 would seem like "oh just $8 and I can have a personal website? easy!" so I'd say keep the price as is.
They're competing with WordPress which is much cheaper and more fully featured
nothing is overpriced if someone is willing to pay
