Green Monday will have holiday shoppers racing against shipping deadlines

There’s Black Friday, Cyber Monday and then comes Green Monday.

According to Investopedia, Green Monday is "one of the retail industry's busiest shopping days, occurring on the second Monday in December."

eBay claimed to have coined the term in 2007. "‘Green Monday’ continues to be a big online shopping day and has consistently ranked as one of eBay’s top five sales days of the year," the e-commerce company said on its website. "In fact, in 2017 it ranked as eBay’s third-highest sales day during the holidays."

However, holiday shopping on Green Monday this year may not guarantee your gift still comes on time given widespread supply chain issues and the fact that some shipping deadlines have already passed.

FedEx shipping deadlines extend from Dec. 9 to Dec. 15, depending on which shipping options customers choose. 

"The busiest time of the season for the Postal Service begins two weeks before Christmas," USPS said in a statement. "It’s expected that customer traffic at all Post Office locations will steadily increase beginning the week of Dec. 6, with the week of Dec. 13-18 anticipated to be the busiest mailing, shipping and delivery week of the season."

However, FedEx is warning that customers could see delays in their holiday shipments after severe weather ripped through at least five states, leaving widespread devastation Friday.

UPS is urging customers to ship their packages now, with Dec. 23 being the last day for on-time deliveries with "UPS Next Day Air."
