It is for "exact shipping" They will arrive with postage due, probably 50 cents, you pay when they arrive. If I shipped all the thousands of items I sell here each year I would be totally broke. I am a senior, age 70, on a fixed income with M.S. I am disabled. Sorry but that is all I can do is to offer nice things and everyone must pay their own postage if they win the auction. If that is not OK, then you will have to buy seeds from someone else. So sorry, Grace
