CHICAGO (WLS) -- Saturday is Nov. 7, the inverse of 7-Eleven.
Only on Saturday, 7-Eleven stores will allow customers to name their own price for any size Slurpee - that can be a penny to $100.
All proceeds will be donated to Feeding America, the nation's largest domestic hunger-relief organization. The non-profit's website said its network of 200 food banks feeds 46 million people across the country.
