Pre-sales question about WP Bundle License

Hi! I want to purchase the word press plugin bundle to use it my client sites.

1. From your web site, you mention that we could install the bundle in all our client web sites with extension license. Isn't it that the $169/year is the extension license that include all the WP File download manager, media manager, etc..?

2. How much is the fee after one year? What if I intend to only continue to use one or two of the plugins in the plugin?

3. Could I continue to use the existing plugin if I do not pay after the license expired after one year?

Thanks!
