Aluminum Intake Shipping Weight/Cost?

I've got an LD4B that is surplus to my needs and I want to list it for sale but I need to know how much it will cost to ship. I don't have a scale to get the weight for an online quote. Can someone who's shipped a standard small block aluminum intake give me an accurate weight for them. I realize the box will add a couple pounds.
mine was right around 15 pounds shipped
