Bad Bot! You stripped out the only important part of the article:

For the special Limited Edition version Valve has said:

You need to be in the United States or Canada.
Your account needs to be in good standing.
Your account needs to have made a purchase on Steam before November 2023.
Only one unit may be purchased per account.

If their experiment with this extra Limited Edition model goes well, we may see others come in future.

Additionally, their FAQ also notes for the normal 512GB and 1TB Steam Deck OLED models you will only be able to purchase “1 model of Steam Deck OLED per customer per week” but they plan to relax that when they’re confident they can meet demand.
