(KCEN) -- If you're still making your list and checking it twice, you'd better get a move on.

If you use regular parcel post and want your package delivered by Christmas, get it in the mail today.
For first class mail you have until the 20.
For priority mail you have until December 21.
And for express mail you have until the 22.
