FYI, if you order a full bag from an online homebrew shop, they tend to kill you on shipping. But, if you 50 lb bulk (not full bag), most places count that toward free or reduced shipping.
Last time I ordered grain, a full 50-lb bag was going to cost me another $45 in shipping. Buying 50 lb by the pound was a few pennies more per pound, but shipping was only $8. When it arrived, it was the full bag (not separately bagged). Go figure.
