Jet.com Warns Customers of Holiday Shipping Delays

The crush of Christmas shopping online is beginning to take a toll on retailers. Buzzy e-commerce startup Jet.com last week became one of the first major retailers to tell customers its packages may not arrive before Christmas. The company announced in emails to customers and on its website that it cannot guarantee delivery of merchandise in time for Christmas except items eligible for pricey two-day delivery. That makes it one of the first major retailers to make such an announcement, though a full week still remains in the holiday shopping season.
