I also have Potassium Iodide saved for if we ever need it due to a nuclear plant explosion, or worse. I have two in my purse,and a box of 20 for each member in our family. It only costs $9.99 a box too. We live not too far from a Nuclear plant-- and with the increased threat of terrorism- one must be prepared.
I ordered directly from the company- and they didnt even charge shipping and handleing!
