The last Sears catalog was the 1993 spring & summer, there was no 1993 Winter catalog. In 1993 Sears discontinued the catalog and closed their catalog distribution centers.
Might be splitting a bit of hair but my last Sears Fall/Winter catalog is marked ‘92/’93 and is also marked good thru July 15, ‘93. Mine is right over there on the book shelf. I keep many old catalogs ‘cause sometimes I just want to know where stuff came from-——and there is a lot of “stuff” hereabouts.
In hindsight, Sears should have put the catalog on line and set up an internet store - an Amazon.com like operation. Of course, hindsight is 20/20 and I don’t know that it was foreseeable back in the early 1990s.
