If you're scrolling through hot deals this Cyber Monday week, don't forget that the deadline for sending packages to arrive by Christmas is only a few weeks out.
With recent postal delays, you don't want to wait to ship items this year.
Mason McCarty runs a shipping store, Safe Ship, and is enjoying this last calm before the storm.
"I will have a line out the door in the next couple of weeks," he said. "I will have 10 to 15 people in a line all day long." He says the first thing you need to know is that prices are up on all services this year.
"Pretty much down the line you are going to see a 5 to 10% increase," he said.
McCarty warns prices will be even higher the longer you wait.
"If you are one of those that want to go Priority Mail," he said, "you need to get those out before the middle of December. It's not worth waiting until the last minute and counting on a two-day Priority shipment."
