Can I buy WoW Token without subscription?

Hello, I have a question regarding the purchase of WoW Tokens. I'm curious if it's possible to buy a WoW Token without having an active subscription to the game. I understand that WoW Tokens can be used for various purposes, including game time, but I'm unsure if the ability to purchase them is tied to having an active subscription. Could you please clarify this for me? Thank you in advance for your help.
