This is not exactly the way it works.
In the Selling Preferences area of My eBay, there's an eBAy Express header. Click on the "show" link to the right, and it will open up to show you if you are qualified to sell on express and give you the option of being included or opting out.
These are the requirements for sellers who want to be on Express:
Maintain a feedback score of at least 100 or more, 98% positive or better.
Maintain a public feedback profile.
Be registered as a U.S. registered seller, or Canadian registered seller shipping from the U.S.
Support your listings with a PayPal Premier or PayPal Business account.
Ensure your PayPal account settings are set to ship to unconfirmed addresses or make sale-by-sale decisions ("Ask me for unconfirmed addresses").
