I get my coal in a bulk delivery from Benjamins in North East, the next town down from Elkton on Rt 40. Benjamins price is $213 per ton with a $25 flat delivery charge for us (we're within 5 miles of them). Since you are farther, they may charge more. If you are looking for bagged I think there is a good source in Quarryville, PA, another member, sourbeer, gets his bagged from there.
