There is very little hassle in building a sandbag and the ones already available are pricey. I put mine together for less then $30. I ordered a large canvas duffle which was the most expensive part at $25 shipped to my door. I then took 100lbs worth of water softener salt I had sitting around and broke it up into 20lb batches. I double bagged that in contractor trash bags which are a heavier mil then regular trash bags, made sure to get most of the air out and then duct taped them closed. I have been using it for almost a year with no problems yet.
