The top ten vendors

I was reading an interview with the new president of Beall's (an 80-unit department store chain in Florida), and I was struck by this comment regarding her past experience heading the men's/boys' business for JCPenney:

We narrowed it down to the 10 top brands, then tried to make the big ones bigger.

Concentrating on your biggest suppliers is not necessarily a bad idea, of course, but I just wonder how she would feel if (as is likely to happen) she finds that many of her suppliers take a similar approach to their retailers, and see limited value in spending a lot of time working with Beall's, which is unlikely to be in many top ten lists.
