"Customers are being more deliberate about where their discretionary dollars are going as prices at the gas station and grocery store eat up a greater share of [their] wallet," Wayfair CEO Niraj Shah said on a call with analysts Thursday.

"We have also seen many of those discretionary dollars flow away from goods to services, especially travel," he added.
