questionshow do i find a past deal info (such as specs)?


You have a few options including using the advanced search. By clicking the links on the deals that turn up you possibly could find a deal which has been reactivated unbeknownst to the original deal poster.
At the very least, it could take you to the vendor's site where you might be able to discover a similar deal.

(By "specs," are you referring to spectacles such as eyewear, or specifications?)


Can you give us a little more info? That would help a lot.
