Does any one know where I can get free promotional items in regards to cancer awareness?

You have to ask companies, preferably local companies, if they would be willing to donate their time/ resources and make t-shirts and cup, etc. for your cancer awareness efforts. Some companies only donate a limited amount of things, others only donate to 501(c)(3) organizations. Ask around, and I'm sure you'll find some company that will be willing to donate. Good luck!
