To end your subscription, simply return your product to Grover at the end of the minimum rental period.
The return label can be found in your Grover customer account. First, click on the product, then the button "Request return label." Here you can download and print the label to return the product for free. It is best to hand your return package to DHL at least one day before your next payment is due so that the next month is not charged.
Once your package has been scanned by DHL, your monthly rental payments are stopped. The subscription will end completely once the product has been received and successfully processed by Grover.
