Configure your Rack Extension subscription Pack using the Subscribe-o-meter. It's the full price that is counted in the Subscribe-o-meter. Rebates and promos have no effect. Once a product is added to a subscription, its price doesn't change, even if the developer releases an update and raises the price.
Not all Rack Extensions are available for subscription; it's up to the Rack Extension developer to decide if they want to participate or not. The "approved" Rack Extensions are listed in the Subscribe-o-meter, and have an "Add to subscription" button on their product page.
When you are happy with your Rack Extension selection, check out by clicking the Subscribe button. After checkout, you are taken to a download page, where you can download your selected Rack Extensions.
The shortest period to subscribe to a specific Rack Extension device is 30 days – the so-called Exchange Lock period.
You can view your current subscription on your Products page at any time.
