The start-up trying to undercut Amazon is running into Christmas delivery problems.
Jet.com no longer guarantees deliveries by Christmas for product orders that aren’t marked for two-day shipping. Most of the items that can still arrive on time are household products like toilet paper and groceries.
In a banner on the company’s website, Jet.com warns shoppers that “this year’s holiday gift rush has led to nationwide shipping delays that have affected many of our fulfillment partners.”
The company, which was founded this summer, attempts to compete with e-commerce giants like Amazon by shipping some of its products and partnering with retailers to ship the rest. The start-up rewards customers who make big orders or ones that can be fulfilled at nearby centers with lower prices, according to the Wall Street Journal.
In an interview with Fortune, Jet.com’s chief customer officer Liza Landsman said that only about 500 of the 1 million shipments Jet.com has processed in December will miss promised delivery dates before Christmas. She said that while Jet.com only provides delivery estimates on the site now, it plans to roll out exact delivery dates in the new year. “Our goal for this month was to hit $44.9 [million in gross merchandise sales], and we will hit it,” she said. “Last week we just hit our 2 million member mark. Every performance mark that we have set we are hitting.”
FedEx and UPS are expected to deliver a record 630 and 317 million packages, respectively, this holiday season, according to Bloomberg.
