The first link you posted is where I got the prices I already posted, and there is no "Offer Details" link that goes to the second url you posted when accessing that site from my geographic area. The only U-verse plans/prices that are visible to me (no matter how many "view details" links and similar links I click) are the ones that I previously posted.
Here is what I see if I click on the "View Details" link on the above page (same plans/prices, just a different page format):
No where on either of those pages could I find an "Offer Details" link.
AT&T has always had different DSL and U-verse plans and prices for the legacy SBC areas and the legacy BellSouth area, and that is not likely to ever change. I suspect that finding a backdoor entry point to a page that was not intended to be viewed by a second class legacy BellSouth area dweller is what caused problems for the OP. Just because you can find a page with an offer that is not meant for you, doesn't mean that AT&T is actually going to allow you to sign up for any plan described on that page.
