Are the new Xfinity "PREPAID" wireless modems in CT stores?

I emailed the store on New Britain ave in West Hartford CT to find out if they have the new Gateway modems (35.00) to go with the new prepaid plan (45.00 for 30 days  that will start on Dec 17Th. I still haven't heard back yet. I have an appointment  set up.  I'd like to know if they have these in stock before I drive over and  stand in line with a mask on. thanks.
