Hook For Shipping

Is there a simple hook for adding $2.00 for each product quantity being purchased? So if I buy 1 product shipping is $2.00 and 2 products shipping is $4.00...etc...

For reference on this, I did what Chris suggested and it in fact works perfectly. Thanks for the tip Chris.

Also, to possibly save you guys some time, don't over think the process here. If your shipping is "Flat Rate" per item, all you need to do is enter that rate as the only "Option" in the option settings. I originally over thought this and added quite a few "levels" incrementing each level by the original rate... ie, $20 shipping cost for first option, $40 for second option (2 units), $60 for third options (3 units). But that isn't necessary, it will increment the flat rate up based on the number of items ordered. Hopefully my feedback here will help some folks.

Really good work on this extension guys. Thanks a bunch.
