I went to order an item and it said free shipping without prime membership. I changed addresses for ship to a PO Box I have very close by because things are often stolen here and it came up new with a extra shipping charge contradicting the original quote without shipping fee that was included apparently. Then I went to change the address back and it said free shipping. Is this confusing or what? Why can't it just be the same free shipping in different addresses? its not some kind of strange thing! I took screenshots of this and will be addressing it with Amazon. This is crazy! Who wants to order online anymore with this garbage from anywhere?
