What local superstore or store can I buy dry ice at?

I am looking for dry ice, for a scientifical experiment. I have looked at my local Meijer, kroger, marsh, walmart. None of these stores carried dry ice. Meijer said they used to but not anymore. If you you could please share any information on where i can purchase dry ice. I know i can get it online but i would rather not pay for shipping and give my credit card number out. Thanks

Check under ‘dry ice’ in the yellow pages, especially in urban areas.
