Possible Prime Membership Deal $7.49/mo for 3 months YMMV

Not available to me through normal channels like Amazon’s home page. I found it browsing through Prime Video, signed into a web browser. To be specific I was here…

I accidentally hit Join Prime Watch Now
It took me to a sign-up page that I can’t show because it’s all personal info. But the deal says, "Confirm Details
Plan – Enjoy unlimited streaming of thousands of movies and TV shows plus FREE Two-Day Delivery on millions of items ($7.49/mo for 3 months. $14.99/month after.)"
I’ve not been a Prime member for a little while. Only join when offered a freebie. I’ve had multiple Prime trials in the past. But I haven’t had one for a few months. Although I think I may have already had one this year.
I don’t qualify for any of the standard special discounts. This is apparently just a hidden deal offer. No idea how long it will be available or anything. There were no other details than what I’ve reported.
