When customers come to the bookstore to search for books, sometimes they leave with information on a piece of paper instead of a book in hand, because they want to “think about it.” In case they decide to order the book, make sure your bookstore name and contact information is on that piece of paper.
Business cards with store information (address, phone, hours, etc.) work well, as do bookmarks with the same information. Just leave space on the back for writing. Another easy fix is to create a mini-letterhead (4.25 x 5.5″) that you can print 4-up on a piece of 8.5 x 11″ paper. Or if you’re mindful of the environment and like to use scrap paper, create an ink-stamp with your store information to stamp that paper before it leaves the store.
With any method, point out the contact information to the customer. “Here’s our number. My name is Beth. But if I’m not here, any of the staff can help you.”
