Mailing Gift Packages through USPS
A set of Christmas/New Year packages that I sent out in December.
Since joining the /r/rabbits community, especially the IRC channel, I have been sending many more gift packages to people all over the world than I did before. Frugal as I am, I did tons of research to figure out what would be the most economical way to ship these packages to everyone. Some caveats though is that I did not try to figure out how to ship something enormous or extremely heavy.
