[CentOS] enable repo download and save but no install

Is there a way to enable a repo, and ask it to download a package and 
all dependencies
and save these files to a given directory then some time later execute a 
command
to install those files that were saved.

Is that possible?

I would like to take a snapshot of something like VLC on dag and always 
install those same vlc packages and dependencies
that were saved locally. Not go out over the net and install them the 
next time. I'm not concerned about
updates to this package.
