Well, you have to take my location into consideration. I live 2 miles away from 4 apple orchards. That being said, I pay 20 to 25 dollars for a bushel of apples.
I pay 10 to 15 dollars a bushel for drops. Drops are on the ground, and best used in apple sauce. Some of the apple orchards I have been to charge by the type of apple vs. a straight bushel price.
I would imagine the farther away you get, the higher the price due to shipping costs.
