Both Kaspersky and Ultra Antivirus has something called an introductory price, which means that the price you paid for your initial subscription was discounted at the time of the purchase. Future renewals will be billed at the normal, non-discounted price. Introductory price also applies to purchases done during sales, such as Black Friday.
This can lead to your subscription cost being higher than you may have expected. The price of your renewal will always be visible on your dashboard, and the price will also be communicated to you through email before any renewals take place.
If you have any questions regarding your subscription, please don't hesitate to contact our support for further clarification.
