selective shipping charge

[Craig Hairston]

My question is similar so I hope it's OK to jump into this thread.

I have a new install V1.3.9h
We offer free shipping on items when the order is greater than $75.00 so we still have to use our weights for small orders. Everything is working fine so far with USPS, UPS, and using free shipping options >$75.00

EXCEPT

We have also indicated that certain (very few) overweight items are exempt from free shipping. Is there a way to force a shipping surcharge in attributes or some other way so when these few heavy items are ordered, that the additional shipping surcharge will applY?

the store is www.scplaceonline.com/zen/

Thanks,
Craig
