Appliances can also be categorized as emotional purchases -- meaning it's likely the consumer will want to see the product before buying.
People want to go to the store to see if it's going to look good, if it's going to fit in their space and if it's a device they can operate. "It's hard to return a washer and dryer once it gets delivered to your house and you haven't looked at it and you can't figure out the buttons," Grannis says.
Appliances are another product that fell victim to the recession, though.
"We see increase in appliance sales every couple of months. People who haven't replaced [an appliance] in eight years finally say 'Let's get a nice one,'" Grannis says.
