Crown Books. I worked there from 1987-1989 as a manager. The chain died under a flurry of controversy after scores of buyouts in 2001.
Chesapeake Knife and Tool. I was an assistant manager from 1989-1991. It quietly faded away after slowly dying in 2006.
Gamekeeper: I worked there one Christmas in 1991 or 92. It went belly up in 2003.
Cargo Furniture. I was a manager at the Springfield and the Tyson's Galleria store from 1993-1996 when I finally left to join the tech industry. Right after I left, there was huge political turmoil until it got bought out by Pier One Imports, then went online-store only, and finally died around 2004.
The only place I worked selling anything that is still up in Nancy's Buttons, which still tours the convention circuits. But that's a one-woman operation, mostly. I worked her table a variety of conventions for many years, and kind of think I'd like to do a few more if I could justify the cost of hotel and travel to do so :)
