One user should have only one subscription. You don't need to purchase two or more subscriptions.
Since if you subscribe multiple times (get 2 or more subscriptions), you will be charged separately for each subscription. However, when you purchase Subscription B, your active Subscription A will be canceled automatically. It means your Subscription A will remain active until it expires, but it won't be renewed automatically when it expires, and you won't be charged for Subscription A renewal.
Please make sure you don't buy more than one subscription. Something may go wrong, you may think your purchase is unsuccessful and try one more time. As a result, you may end up getting 2 subscriptions and you'll have to pay for both. If you face difficulties when buying Boosteroid subscription, contact us at [email protected] or in the support chat available in the lower right corner of the boosteroid.com main page. The team will be glad to assist you.
