weight product "0"

i need to sell product with shipping cost included in the price and others product that have to be sold with weight calculation for the shipping cost…

So, i thought: if i put a weight really low ( 0.001 Kg ) to the product i want to leave out from the shipping cost, and i put a range from 0.0001 to 0.0002 and a shipping of 0€… probably the plugin will not add any shipping cost…. nad so it was!!!

But, i mean: could you put in the plugin a feature to exclude some product from the weight calculation?

Thanks
