Yes; this wasn't really an I Love Lucy store as such. It was a store (and I'd swear it was what has now become "Villains in Vogue," but that could be the suspect memory of a 40-year-old who never had the greatest memory in the first place) that carried a good bit of Lucille Ball-related merchandise, more or less gathered into one area.
Universal actually has a small attraction called "Lucy: A Tribute." It's a little walk-through museum. It makes sense, therefore, that they'd have a shop related to that.
