Am I allowed to send one buyer 2 different invoices for the same purchase? The first being for the cost of the items being purchased. The second being for the cost of the shipping and shipping materials once the package has been packed & weighed for shipment. Some lady tried jumping all over me telling me she thought I could get the wrong kind of buyer and implied they could scam me. Then after I proceeded to tell her that the second invoice clearly explains that it's for the shipping for the products I sold in the previous invoice and I include the previous invoice # as well. So basically is it ok to send a second invoice for the shipping on items I previously sold if I don't know the shipping amount to add into the first invoice right when I sell my items?
