I've decided that I will buy many dozen frozen tamales from a local establishment and ship them to a couple of places in the United States, including one to the east coast. I plan to ship the tamales with ice packs of sorts. Only thing is, I cannot find insulated containers (or foam containers) anywhere. Trust me, I have looked everywhere (online and by telephone, that is), including through the U.S. Post Office, UPS, FedEx, Staples, OfficeMax, Container Store, etc. None of these places carry the insulated containers.
There are SOME online stores that do sell them, but they sell them in bulk; I only need maybe 2-4 insulated containers. What more, I would not be able to check out the size of the containers before purchasing them.
