DENVER -- The post offices will be busy this Monday because it's the last day you can ship packages via Standard Post, in order for them to arrive on time for Christmas.
FOX31 Denver's reporter Greg Nieto has a few tips on how you can avoid that long line and save money.
One way is the self-service shopping kiosks, that you can use even when the post office is closed. You can also go online, print everything you need and have your carrier pick it up the next day.
The deadline for First Class and Priority Mail is December 20. You can use Priority Mail Express as late as December 23 for your items to make it on time.
