What is the cost? How much is shipping?

What kind of corn do I need to burn?
The units use shelled, whole kernel corn. The best corn is clean and dry (15% or less). Clean corn burns great, but dirty corn with excessive fines and large debris like cobs and stalks may cause some problems. Corn can be purchased from most corn farmers or elevators.
