The price is $7.75 per cu/ft.
You can purchase at www.nyccontainer.com.
PLEASE go to the "cost" page to read about how it works.
The price is by CUBIC FOOT so a box that is 2 FT by 2FT by 2FT would be 8 cubic feet or around $60. You can make it as heavy as you want and it will be on the playa when you arrive.
