Morning Lookers - Afternoon Buyers

I'm working the front of the store today and have noticed that although we get many people walking through the store there are very few sales in the morning hours.  It has become habit to wait and check on our daily sales until late afternoon.  Why is that?  Many of our products are a little more higher end maybe and people need to think about their purchases.  But, we have many smaller unique items as well.  This much I know, people buy candy at all hours of the day because 90% of the people that walk in our store have a small white bag from Tremblay's Sweet Shop down the street.
