This looks slick! One idea I'd recommend is to look at what the user is subscribing to and monitor for when deals are available and alert the user to that. For example Xbox Live is usually $60/year, however there are frequent sales (Amazon, eBay, etc) that offer discounts to $35/year. Similarly with music subscriptions, etc. There's your revenue model as well. Because you're saving the user money they can kick you back a few bucks (maybe a percentage of the savings).
