Under Lens, and Shipping - select "No option",
and on Checkout, leave default "Flat rate = +$0.00" option.
Came through every time for me.
No shipping payed, and deliver far faster than any other orders I've placed.
EDIT: Oh, you might want to add 2 or 3 plastic ordinary lenses with order, they are only $0.50 each and sometimes come in handy.
EDIT 2 : Link for those plastic lenses
