My one S&D book was a CL hardbound, which looked, when it arrived, about how a hardcover looks after I own it for a week. Slight compression of the ends of the spine corners, and the top, outer front corner of the cover bent/curled in slightly. About 10 trips in and out of the bookcase and my clean books look like that. (Forget trips to and from games in a duffel bag, where the fabric grinds off the color of the corners.)
Essentially, it was not "mint". . . if I'd not known it was an S&D copy, I might not have noticed.
