# Try it out on Testnet

T**ry out the application by visiting a checkout page directly:**

## This is an example for a theoretical web comic subscription:

{% embed url="<https://debitllama.com/buyitnow?q=a0d82581-1442-453c-8c6d-0ac6e0402692>" %}
The subscription is on BitTorrent Donau Testnet
{% endembed %}

The Subscription will cost 1000 BTT per transaction and will be 5 payments processed with the interval of 25 days! Total payment after the end of the period is 5000.0 BTT.

If you don't have an account yet, **you need to register to log in**.

Then you can do everything else on the checkout page.

The subscription requires you to

1. Have a **BTT Virtual account on Donau Testnet and some testnet tokens**
2. If you don't have one, you can create it directly on the checkout page
3. If you have one but the balance is insufficient, you can top it up on the checkout page
4. You can create a new virtual account for each subscription separately to have better control over your spending.

After you have the account click **Finish checkout**.

**If you added a passkey on the dashboard, you will need to authenticate first.**

The**n enter the account password, click subscribe** and you have created the subscription.

We are working hard in the background to fulfill the subscription payments for you and your account will be debited in 30 minutes. You have time to cancel the subscription till then, and you will find more information in the application dashboard!
