I asked MD Anderson but they won't take them back, said something about if for some reason the cans needed to be recalled them they would have to have documentation on who they gave the free stuff to in order to notify them and that it was more work for them, blah, blah, blah.

I also called the supplier but they said nope too. I will call one of the local hospitals or something.

Thanks for the advice! I just want to bless someone else with it.
