Key Collector Comics is free to use, but if you want a whole bunch of other helpful features (alerts, assorted snazzy articles) you can subscribe for $1.99 a month or $19.99 for the whole year. Based on how much this website and its app contains I would say that is quite worth the price. For example, once I made my account a paid one I took advantage of some alerts about books that might become, "Key," issues to dig in my back-issues and pull-out comics that I thought were worth all of a dollar but depending on what the future holds might go for a chunk more someday. Even if you are someone who doesn't do much buying and/or selling of comic-books, the lists and writings are full of fun facts, trivia, and otherwise I'd say they're extremely informative if you just like learning about comics.
