“If it’s in stock, we have it” (store sign)

“If it’s in stock, we have it” is a jocular store saying that has been printed on many images. “If it’s in stock we have it, and if we ain’t got it, you don’t need it” was printed in the Minneapolis (MN) Tribune on September 23, 1968.
 
“If we don’t have it, you don’t need it” is a popular related saying.

Bonanza’s lease recently changed hands, and new operators are making changes that ruffle some locals, like removing the kitschy “If it’s in stock, we have it” marquee, and replacing the adult department (think The Hangover) with Kidzworld (think of the spectacular success of the MGM theme park …).

The prepay sign, which is known as tautology to word nerds like me, ranks right up there with “If it’s in stock, we have it,” “Unsolved mystery” or “Free gift.”
