Well, this closing lets me exercise the Cent (¢) sign we discussed just yesterday!
You can't fault this place for locking themselves into anything -- as long as they had one item in the store that was less than a dollar, they were within their operating parameters. Apparently it didn't help. Decker Center is one of a number of little strip malls down the west side of Decker Boulevard, many nowdays run by immigrants -- Decker, in fact, is designated as Columbia's "International Corridor".
According to this PDF 99 Cents had a 2010 business license, but I'm going to say it didn't make it too far into 2010, because I've been noticing the empty storefront for a while now.
Does anyone remember if this is the strip mall that had Columbia's first CD store?
