Jodi in Cleveland,
Here are some ideas, hope they help:
Do a Google search for "coffee donations in Cleveland" or "winery donations in Cleveland" or "restaurant donations in Cleveland"... You get the idea. Sometimes you'd be surprised what pops us.
Try your national brands for free coupons: C&H Sugar, Sweet Baby Ray BBQ Sauce, Gum Dental - I've had luck with these in the past, but haven't tried yet this year. The big conglomerates (Proctor & Gamble, Kraft, etc) never had luck with as they donate on a huge scale to big organizations.
Try all your coffee shops, golf courses, skating rinks, bowling alleys (AMF is national I believe, and I did get a favorful response from them), local cupcake and cookie shops (great for the bake sale during your fundraiser!), local theaters and museums, aerospace museums, gymnastics or karate lessons, zoos and funderlands, if you have any distribution companies (beverage, chips, fruits/veggies) sometimes they will donate items.
Good luck!
