Query: I won't use it again

I recently ordered an item from Amazon. I did it on-line and I'm very disappointed.I wanted a Styrofoam exercise device that is half cylindrical in shape. In the display it's called a half-round. I chose the shape from those portrayed in the catalog. One half round, 36"long and the curved portion is either 6" in diameter or 3" in radius, whichever way you choose to describe the curved portion.What I received was a full-round cylinder that is 36" long and 6" in diameter. I'm not going to try to return it. Once bit, twice shy is my opinion.From now on I will only order books from Amazon. At least none of my book orders have yielded me something I can't use.I sure wouldn't recommend ordering Styrofoam forms on-line.
