Handling fees, along with UPS/USPS fees, on a "per item" basis?

Thank you for the response. :-)

All products for this store will include 1 box (custom-made by the client) that the product is shipped in. All products are the same size and weight, so they all fit in the one box. The $3.00 Handling fee is going toward the price of each custom box, time for a worker to pack the product in the box, plus a little extra for gas to run the boxes to the nearest UPS/USPS store.
The item/box is where I keep getting confused, because when I think of the box, I think of the custom box for the store; while UPS and USPS considers each box by what they would normally use to ship with (using some kind of size/weight ratio formula of some kind...?).
Each product will ship in the custom box, which will be 3.0 lbs each - which includes the weight of the product and the weight of the box & its internal packaging.

In the Configuration / Shipping/Packaging, this is what I have set:

Shipping/Packaging

Title Value Action Country of Origin United States Postal Code 85396 Enter the Maximum Package Weight you will ship 50 Package Tare Small to Medium - added percentage:weight 0:0 Larger packages - added packaging percentage:weight 10:0 Display Number of Boxes and Weight Status 3 Order Free Shipping 0 Weight Status 0 Shipping Estimator Display Settings for Shopping Cart 1 Display Order Comments on Admin Invoice 1 Display Order Comments on Admin Packing Slip 1

Maybe I need to change the "Maximum Package Weight" to 3.0 lbs.?
I tried setting the per "Order / Box" settings in the UPS and USPS modules, and they both show the same Handling fees applied. I'm guessing the "Maximum Package Weight" setting may fix that?

That could work for us, but I still wouldn't be able to set it to charge a Handling fee depending on the amount of products purchased per order, right? If someone orders 10 products, we only want to charge $10.00 instead of the $30.00 it would be if we did the $3.00 Handling fee "per box." We also don't want to charge only $3.00 for an order that large (if we set it to "per order").

We will do one way or the other if we have to, but I wanted to check if there was a way to combine the two methods first.

Thanks again,
