Online retailers have bumped back deadlines and are offering deals on express shipping after weekend snowstorms kept holiday shoppers home in large areas of the East Coast.

Amazon.com has extended the cutoff for standard shipping by one day, through Monday. Macy's Web site is offering free shipping through Monday, and J.C. Penney has half-off express shipping through Tuesday.

Luxury seller Saks Fifth Avenue is offering free shipping through 2 p.m. Wednesday.

The moves are a bid to capture business from snowed-in shoppers in the final days before Christmas.

The weekend before Christmas is typically one of the busiest of the year. But snow that stretched from the Carolinas to New England closed malls and kept shoppers off roads.
