Sunday along Michigan Avenue, people braved the cold weather to tackle those long wish lists.
"It's a little unbearable but we're getting through," said shopper Itzel Sanchez.
The amount of online shopping has skyrocketed over the years, just ask Anthony Hayes.
"There is way more shopping online than there is in the store so it's a lot of packages that have to go out," he said.
In order to get your packages on time for the holidays postal workers like Hayes are clocking in on Sundays.
"If we didn't do Sundays it would be crazy, we'd be bombarded during the week," he said.
So Hayes and is hitting the streets to make sure holiday packages get to you right on time.
"People are wrapping gifts, sometimes they get the gifts and have to transport it to other places," he said. "It's a struggle so we have to get it out here to our customers."
With 10 more days until Christmas, don't be surprised to see your local mail carrier working earlier in the day during the week, and now, all weekend long.
The post office will continue their Sunday delivery next Sunday, as well.
