$20 up to 600lbs and after 600lbs it is pro-rated at $65/ton and it is a $3 fee on top of the price IF you pay with a credit card. Also they do not accept American Express.
The cost per ton is $62. If you divide $62/2000lbs (in a ton)= $0.031 per pound. So around 3 cents per pound. But- The minimum charge is $20 and that's for the first 640 pounds that is disposed. They also add a $3 fee if you pay with a debit or credit card.
