Seeing different Amazon Sign-In pages

I’m using Amazon Simple Pay with my web site.
When I click on the website Amazon pay button, I next see the Amazon Sign-In page.
On my computer it just shows “Sign-In With You Amazon Account” with sign-in fields all the way on the left of the page. That’s all pretty much.

However, when I click on the website Amazon pay button, using another computer, I see an Amazon Sign-In page with “Sign-In With You Amazon Account” in the center of the page and I see “Sign-In - Select Payment Method - Confirm Payment” across the top of the page, and I see “What is your email address”, plus “I’m a New customer” and “I’m a Returning User” choices on this Amazon Sign-In page.

Why does my computer show a different Amazon Sign-In Page?

thanks. yes I did clear cookis.
Any other help would be appreciated.

It seems that Amazon recorded information about your visits.

Try to clear cookies in your browser and most likely you will see “I’m a New customer” and “I’m a Returning User” choices on the Amazon sign-in page.
