How can I help WalMart employees carry out their strike?

My resources are severely limited but one of their stores is nearby. Anything I can do to help out?

Only thing I can figure is to print out pro-employee strike messages on dollar-sized paper to give them at the register. But I refuse to shop there, so, no.

Any positive ideas appreciated. I don't go back to my threads unless alerted, so if you have an idea, please DUmail me.

Thanks!
