Can anyone think of some cheap fundraising ideas?

I would like to start a fund raiser but have very little money does anyone know of anything I could sell through the mail with out any face to face contact only mail and phone that I could do for $20 dollars or less. I'm looking to sell something that is in demand and cheap to buy that people would be willing to order through the mail. I would be willing to spend up to $50 dollars any money making ideas?
