Nearly a year ago Adobe made a big move and aquired Macromedia. When doing so they made big announcements (though I much prefer John Gruber's unspun FAQ) and generally hyped the deal as best they could.
Apparently, they forgot make their online store backend read the pressreleases:

If you aren't fluent in HTTP, that is Opera asking for a page on store2.adobe.com, and the server responding "well, we've moved the page over there for now but by the way please remember these cookies and send them next time you visit us at macromedia.com".
