Hi Joe,

It seems there is a shelf live on the allertest people can buy so you about
have to wait until you have a number of items needing testing then order the
kit one at a time for testing. I also HIGHLY recommend seeing O. Richard
Norton's book "Field Guide to Meteors and Meteorites" as he has some
household items you can safely use to test suspect specimens. Best!
