Gene Simmons has finally announced his long-gestating The Vault box set -- and, Kiss fans, we hope you've been saving your money.

The 150-song collection of "never-released-before songs written and performed by Simmons," which features "notable rock 'n' roll artists including member of Kiss past and present," won't be available in stores. The set is being sold exclusively online, and each copy will be delivered to you personally by Simmons in one of three increasingly expensive ways.

For $2,000, you can attend one of 21 "Vault Experience" events across the world. In addition to the personalized and autographed box set -- which is "packaged in a massive 12” x 12” x 6” leather-bound commemorative book featuring dozens of never-seen-before images of Simmons over his 50-year career" -- fans will be treated to a "songs and stories" playback and Q&A session, and granted one-on-one photo, autograph and video time with Simmons.

For $25,000, you can attend one of 11 "Producer Experience" events, which include everything above plus "an intimate hour in a recording studio with Gene listening to tracks from The Vault" and an executive producer's credit on the set itself.

Finally, for $50,000, Simmons will deliver all those goodies right to your home, where you and up to 25 friends can spend two hours with the "God of Thunder."

So far, no track list has been revealed for The Vault, although it will reportedly include the demos Simmons cut with Eddie and Alex Van Halen prior to the recording of Kiss' 1977 album, Love Gun.
