Microcenter: $100 off *any* laptop coupon

Microcenter is offering $100 off any laptop coupon to new customers when you sign up and create a new account.
A new account is one where the email address and cell phone number don’t exist in their system, and they accept the cell phone number. (I think Google Voice Numbers and some others will not work.)
I don’t have a direct link to the coupon, it will appear when you go to their laptop section and scroll down the page. They have a $15 off coupon that appears sometimes, and sometimes it’s $100 off a laptop.
I’ve copied a screenshot of the offer and attached it to this post.
Here’s how I get it.
1: Open a web browser in InPrivate (Edge) or Incognito(Chrome) mode.
2: Open the laptop section at Microcenter: https://www.microcenter.com/categ…-notebooks
3: Accept whatever pop-ups happen like allow location and accept cookies.
4: Scroll down the page slowly and at some point the coupon offer will appear.
5: If the coupon does not appear, or a different coupon appears, then close the browser and start over.
6:When the coupon appears sign up for a new account. They’ll text a verification link to your phone and your email address.
7: Accept the verification on the phone and they’ll text you a link to a unique one-time use coupon tied to your account.
I used the code they texted me to buy a refurbished HP laptop for $144 out the door.
I don’t think the coupon works on open box items, but I did not try.
