Once Delicious Library 2 is installed you can purchase a license for $40 at any time by selecting Delicious Licensor from the Library menu.

Delicious Library 2 requires OS X Leopard (10.5) to run. If you own an older version of the operating system, you can still download version 1 and purchase a version 1-only license for the reduced price of $20 (using version 1's in-application store). If you later purchase Leopard, you can upgrade to version 2 for another $20, so you'll end up paying the same as if you bought version 2 now.

If you purchased Delicious Library 1 before December, 2007, you can upgrade to 2 for $20 (from the in-application store) . If you purchased Delicious Library 1 after November, 2007 and before we reduced its price to $20, you can upgrade your license for free (again, using the in-application store) or wait for us to e-mail you a free license in a few days. Your version one license won't work in version two, and your version two license won't work in version one.

Bluetooth scanners are also available through the built-in store for an additional $215, but only when purchasing a license, because this is a screaming deal.
