I think this has been covered a few times so if this doesn't work try
searching the archives. 

This is not tested, but putting something like this on your checkout
page should work. This should give a $3 discount to the order if ITEM1
is in the cart and there are more than 7 items in the cart.

[if ordered ITEM1SKU#]
[if type=explicit compare="[calc][nitems] > 7 [/calc]"]
[discount code="ITEM1SKU#" interpolate=1]$s - 3[/discount]
[/if]
[/if]
