For FEDEX and UPS shipping deadlines for your Christmas packages you have a little more time, but not much, as many of those deadlines for domestic shipping begin Tuesday, December 19.

Don't forget how busy this holiday season is, so you also have an option to thank your mail carriers who are working hard. Remember it's a $20 max value of a gift to the carrier, but not money or a card that can be exchanged for money.

Amazon is now allowing customers to tip drivers a $5 gift card. You can submit the tip by searching "Thank My Driver" on the Amazon website or app.

Better get on the stick!
