I have a cause that I raise money for as well. I purchased 200 gourmet coffee lollipops. I keep them on my desk with a sign stating the cause...and people have been buying them like crazy. I don't have to ask people for money (which I am uncomfortable with) and the people in my office are totally awesome.
I have nearly sold out of the first batch and will be ordering more soon!!
I'm also doing the breast cancer walk here in Michigan in October and I plan to make a quilt and hold a raffle with ALL the money raised to go towards my goal for the walk.
Good Luck...and raise lot's of cash.
It's a great cause!!!
