So I'm ordering a bunch of stuff from Amazon, naturally when I make an online order at any store I like to order lot of stuff together to save on shipping. But with Amazon it looks like free shipping only counts for items that come from Amazon, and naturally, most things don't, they come through 3rd parties. So I'm guessing I have to pay shipping for each individual item? Problem is, I don't see how much an item cost for shipping, it just tells me the grand total at the end. I don't want to buy a $3 adapter if the shipping for that one item is like 10 bucks. How do I know how much it actually costs without having to remove and readd each item individually? Even doing that does not seem to change the shipping cost, so is it a flat rate for all non amazon items in my list?
