Getting a handle on this bulk madness is presumably one of the reasons Duane asked Harry to come up with a list of what each store is carrying. The results were evidently not quite what he had in mind, though, for he asks Corey to do it all over again. When Edgar hears about this, apart from considering it comical, his next thought is that he could come up with those lists in about five minutes, or at least lists of what each store is ordering, separate lists of what each store is selling. Could even combine them in an Excel sheet in some fashion to highlight what the differences are. But then considers that Duane surely knows this, and if he was interested in such, he would ask. So he must be looking for something else.
