Steve Hutt has shared his workings with us in the form of this spreadsheet: (Thank you Steve)
http://www.rvforum.co.uk/files/container.xls Each consignment has been anonymised and the Volume, Value, Fixed Cost are merely
an indication of the workings as is the $1.95 exchange rate.
Play around with the data substituting your own requirements as appropriate.
Shortly, I will provide more contemporary data when we feel we have a viable proposal.
Please use the Shipping forum to comment as you see fit.
If you have worked out your own personal requirements then PM me in the above format and I will update the spreadsheet accordingly David
