Retailers in the US are rolling back their deadlines for guaranteed Christmas delivery to avoid a repeat of problems experienced last year.

According to Shop.org’s eHoliday survey, conducted by Prosper Insights & Analytics, 78.8% of retailers surveyed will set standard shipping deadlines for guaranteed Christmas delivery at least a week before, up from a figure of 73.7% last year.

Meanwhile, only 21.2% will set deadlines at 19 December or later, compared to 26.3% in 2013.

“It’s important to remember that the 2013 holiday season was impacted by a multitude of factors that affected the supply chain in the days leading up to Christmas, including bad weather and a shortened holiday calendar,” said Vicki Cantrell, Shop.org executive director and National Retail Federation senior vice president.

“That said, retailers and their delivery partners this year are proactively planning to make sure they meet customer expectations for delivery and customer service.”
