Unfortunately, the Express version of BounceBack is no longer available on its developer's website, so you won't be able to purchase it. However, the regular edition of BounceBack (version 18) can be acquired from the website of the developer, both in a digital version ($49.95) and as a CD ($64.95). To buy it, simply scroll down on the previously mentioned page and click on the small blue cart icon under the product that you're interested in.
