Existing users of The Bat! earlier versions can opt for an upgrade package, rather than pay the full cost, which gives a significant saving on the full amount. See the Purchase page here for options: https://www.ritlabs.com/en/products/thebat/order.php and here: https://www.ritlabs.com/en/products/thebat/upgrade_policy.php for the upgrades included with each version purchased.
