When adding a weight to a product, am I supposed to *just* put in the weight of the product, or the weight of the product and a box?

In the weight box, if I put in 1 that is equal to 1 pound? If I put in .25 that is equal to 1/4 a pound? Is that right?

I am trying to figure out why I'm getting killed on shipping ... and I think it has something to do with the box size.

For example, if someone orders 2 bath towels, what they pay for shipping is usually in line with what I pay. But, if they order 4 bath towels (which has to go into a 12x12x12 box, I get killed on shipping.

Any and all help will be greatly appreciated!!!!

HUGz! Jules
