I went to check out BookFusion, which at first glance, seems like an interesting idea.

Unfortunately, I could not find anywhere on your site that indicated the cost associated with an individual user account. (Free to signup, of course, but how long is that trial, or what limits will I face? and then how much money will this subscription service cost me?)

End-users have serious account fatigue, and I seriously debated whether I should bother signing up for the site and create yet another login to a web app I might or might not want to use. Please, just be up front about pricing, free trials, limitations, requirements, etc.

If you have a 7-day free trial and I'm currently busy, I won't have time to kick the wheels before I'd need to pay. If you instead limit the number of books or the storage space I can use, just tell me so I can decide if it's worth bothering to test it out. As far as I can tell, you might or might not have a limit for a new/free user, but no idea what that is.

Finally, I see in the settings that you offer an early bird subscriber deal, at $4.99/mo (vs $9.99/mo) and $39.99/yr (vs $60/yr), for unlimited storage. I think you might have better luck with a tiered setup. Someone with a lot of ebooks might find $40/year to be a great deal, but most users likely don't have that large of a collection - they're looking for more of an ease of use and convenience factor. Take advantage of that, and then allow them to move up and give you more money once their collection grows.

$10/year = 4GB storage or 2000 ebooks? (count # of books, and not storage, to make it seem less technical?) $20/year = 8GB storage or 4000 ebooks? $40/year = 20GB storage or __? $60/year = unlimited

or $10/$30/$60 year, with 2000/10,000/unlimited? and only allow monthly payment as an option for the $30/$60 levels?

at $10/year, it would be an impulse buy for most readers, and then you not only have a paying relationship with them right away, you have a whole year to demonstrate the ease of use and utility of the product.
