Where can I buy sandbox land?

Excuse me, I'm a novice in the cryptocurrency world and I've been hearing quite a bit about Sandbox lately. It seems to be a popular platform for creating virtual worlds and gaming experiences. However, I'm a bit confused about how to actually purchase land in the Sandbox metaverse. Could you please clarify where I can go to buy Sandbox land? Are there specific marketplaces or exchanges that facilitate these transactions? Additionally, are there any prerequisites or requirements that I need to fulfill before I can make a purchase? Thank you for your help in navigating this process.
