Send me $21 and $3 for shipping, total of $24.
This CD originally sold for much more, I know the Surplus Shed sold it for over three times this price. It is packaged in a box with instructions for installation which is very simple anyway. I see no need to include a picture here since the main part is just a CD Rom.
***** I have been notified that Surplus Shed is closing out the CD at $21 so I reduced the item to that price with about the same for shipping as they charge. *****
