already have ring plus plan, how to take advantage costco's 1yr offer?

It seems that if I buy a Ring Doorbell Pro from costco ([https://www.costco.com/ring-video-doorbell-pro-with-12-months-ring-protect-plus-plan.product.100377990.html](https://www.costco.com/ring-video-doorbell-pro-with-12-months-ring-protect-plus-plan.product.100377990.html)), it comes with 1 year of Ring Plus. However, I already have a Ring Plus, could I still take advantage of this offer to buy a Doorbell Pro from Costco?
