I'm looking for a specific book.

Just had a phone call.

Customer asked "I need a dictionary for my 6th grader"

"Ok, which one?"

"It's made by Merriam-Webster"

"Well, they have several versions of dictionaries, do you know which one?"

"No, he's in the 6th grade. I'll call the school bookstore, see which version and call you back."

Now, if the school has a bookstore, why would you need to call a commercial bookstore?
