shipping is free in USA ONLY and i never ship package without a tracking number it a protection i use in case package gets lost or get scammed and you must have not used the post office lately cause there was a postage increase
If you offer free shipping, Listia specifies that it must be unconditional. Thus, you're now stuck with shipping this free no matter whether someone uses GIN or not.
I did know there was but it slipped my mind...excuse me for making a humanly mistake and that attitude isn't called for. Good luck with your auctions with that attitude. Goodbye.
