Spent the last several weeks trying to register online but always getting the message that "no covid vaccines are available right now". This is true for any walmarts in the north Huntsville area. I found the same true for CVS. The Madison County health dept was booked through June 8 as of a couple of days ago. Don't know where this rollout is going but it doesn't look like for the pharmacies. You might have better luck trying to register online with A&M. I got my first dose within a week. No long lines. Good luck.
