Query: Expensive shipping

I ordered this item,not realizing the cost for shipping. It is confusing for me when I use Amazon, sometimes the window closes before I know what I have agreed to pay.Just after ordering I looked up the transaction and was shocked to see the charge for shipping for this item. I immediately canceled the order, the item wasn't worth that much to me.Even tho I had canceled the order, they sent it anyway and I was charged for the shipping. Be careful when you order on Amazon, its easy for the order to be completed before you review the "hidden costs".
