Summarize.com beta pricing chart

They are essentially offering a free trial until they fully launch but was a bit more clever with the wording. They were able to build value by displaying each tier with the (future) price scratched out. Signing up for a beta version of anything gives the users a feeling of exclusivity. I personally get the feeling that i'm on the ground floor of something new. So it was a good choice to use "beta"' in the copy.
