This question offers you the opportunity to show off your love for local business! Focus on the sense of community and personal touch a local bookstore provides as opposed to a big-box corporation. What separates may include local events, customer care with a personal touch and community involvement.
"Your store is one of the major attractions of this community. As a regular shopper here, the management is great, and your team does a fantastic job at making each customer experience memorable. This experience is not something you can find in a larger, corporate retail store or even when shopping online."
"A sense of community is an important value to me. This is not something that larger big-box stores, or e-commerce, can provide."
"I see that you hire with discernment. This discernment means that each employee in your store in knowledgeable, an avid reader, and an incredible resource for your patrons. This experience makes all the difference for me. Also, your coffee shop offers decadent treats, and I appreciate that you give 10% of your profits back to the community."
